With three murders in a population of about 1500, over the past four years, the annual work related homicide rate for Winnipeg cab drivers has been 50 per 100,000.
This is about 2 1/2 times the rate for both cab drivers and policemen in California; the same as the rate for inmates in U.S. Federal prisons; and 24 times the rate for all male workers in Texas, based on statistics published in the American Journal of Public Health in October, 1987.
Should this homicide rate continue, our taxi community could expect to lose 7 or 8 more of its members in the next 10 years.1
Note: Included in this report are representative samples of certain technical standards upon which Manitoba Regulation 41/90 relies. They are included here only as a convenience and are not displayed in their complete format. In any official application, the original of the documents should be acquired from the sources indicated and subsequently consulted.
This report will address the Safety Shields issue. The Taxicab Board cannot design a shield, it cannot build shields, it cannot buy and sell shields, and it cannot give away shields. What the Board can do is define what a safety shield must do, such that taxi industry representatives may negotiate in confidence with suppliers of their choice. This the Board has done, and has a reasonable presumption that the industry will take appropriate initiative soonest.
Following an extensive review of the local, national, and continental risk; requirements for safety shields, the activities and progress of a selected array of other jurisdictions, contemporary designs, and availability of shields, the Taxi Safety Shields Task Force has concluded that:
and recommends that:
Little scientific research into the risks faced by taxi drivers has been done. The National Taxi Driver Safety Council, headquartered in Tampa, FL, reports that in 1988, 34,070 acts of violence were inflicted on taxi drivers in the U.S., from which 253 murders were recorded. No such information is available for Canada. From our three murders of Winnipeg taxi drivers, from a population of about 1500 drivers over the past four years, we can only estimate the annual work related homicide rate against them has been 50 per 100,000.
This is about 2 1/2 times the rate for both cab drivers and policemen in California; the same as the rate for inmates in U.S. Federal prisons; and 24 times the rate for all male workers in Texas, based on homicide statistics published in the American Journal of Public Health in October, 1987.
Should this homicide rate continue, our taxi community could expect to lose 7 or 8 more of its members in the next 10 years.
There is no mechanism for the rapid exchange of information relative to this issue, so the group was faced with the potential of significant delays in gathering needed information to make a fast start.
However, the Task Force learned about the National Taxi Driver Safety Council, and its Executive Director, Jim Szekely, in Tampa, FL. Within a conversation with Mr. Szekely, a recommendation emerged that we contact the 2 most knowledgeable people in North America about Taxi Driver Safety:
From discussions with these 2 experts, flowed a substantial amount of useful information, itself quickly leading to a wider array of information sources. Their help dramatically reduced the time needed for a proper start.
All documentation made available to the Task Force, principally the Fox-Decent report, revealed only reference to criminal acts inflicted on a sample of the local taxicab industry.
To gain a better appreciation of the risk here, inquiries to the Winnipeg City Police, the RCMP in Winnipeg and Ottawa, MPIC, Winnipeg Taxi Driver Safety Committee, and the Toronto Metropolitan Licencing Commission were directed.
Disappointing results emerged from these inquiries:
Capt Don Devine in Boston, and Mr. Angelo Noa in New York, have determined that the single most significant driving force behind these criminal acts is chemical dependency. In most cases, the foreground motive is robbery, and typically for trivial sums of money, for "the next fix". Taxi drivers are seen as easy "marks", a mobile cash register just waiting to be opened with remarkable ease.
In a 1988 report, the National Safe Workplace Institute, a U.S. based independent research organization, identified taxi operators as among the most vulnerable workers in society. In their view, shields provide maximum protection and present a simple and relatively inexpensive means to address this "national disgrace". Taxi fleet owners were urged to immediately install protection. For the Institute, "the issue really boils down to protecting lives".
The City of New York Police Department strongly advocates the use of safety shields. In their view, "the single most effective deterrent to taxi robberies" is the installation of a shield. Their analysis of all robberies of taxi drivers in New York City indicates that "...more than 70% would have been defeated had a shield been in place...".
Between 1967 and 1969, there were 10 cab drivers murdered on the job in Boston. As a result, shields were made mandatory. In the 20 years since, not one driver has been the victim of a homicide as a result of an assault from inside the vehicle.
In view of the above, it appears clear that the Winnipeg taxi industry is operating under a false sense of security. True, we pride ourselves that this is "Friendly Manitoba", that we are far removed from the crime and mayhem of the big cities down south. However, a cursory review of recent local newspaper reports, and discussions with local law enforcement officials clearly reveals that the horrors of drug related crimes are already establishing firmly entrenched footholds. Winnipeg can no longer consider itself immune from these risks.
One year ago, the Metropolitan Licencing Commission in Toronto, in response to a rash of murders, assaults, and robberies, commenced a review of safety shields, and of taxi driver safety, much like we did only 4 months ago. On 19 Oct 89, after 13 months of effort, the Commission formally recommended to Toronto City Council that safety shields be made mandatory. It is uncertain how or when that Council will deal with this issue, but a
Twenty years ago, in response to a similar alarming array of murders, assaults and robberies, Boston made safety shields mandatory. They continue to be mandatory to this day, and their presence is credited with a 70% reduction of these types of crimes. Capt. Don Devine, Commander, Hackney Bureau, advises that their dominant fears are directly related to crimes emerging from chemical dependency. Such crimes are most often focused on trivial sums of money.
3. Flint, Michigan
In response to somewhat similar crimes, Flint, Michigan, just 5 months ago, enacted a municipal by-law making safety shields mandatory.
4. Newark, N.J.
In response to somewhat similar crimes, Newark, N.J. enacted a municipal by-law making safety shields mandatory.
5. San Francisco
In response to somewhat similar crimes, San Francisco has recently formed a Taxi Industry Task Force, under the leadership and authority of Deputy Mayor Jerry Lee. They plan a broad overview of both the industry and its economics, along with taxi driver safety.
In response to 5 murders in the last 8 months, Atlanta has formed a Task Force, under the authority of the Director of the Bureau of Taxicabs, Mr. Joseph Hall, to review all forms of taxi driver safety, and is targeting his preliminary report for mid-January, 1990.
7. New York
In response to an awesome array of murders and assaults in the Greater New York area, the Taxi & Licencing Commission in the Woodside Borough, under the authority of Deputy Commissioner Angelo Noa, has just formed a Task Force on Taxi Driver Safety, will conduct an in-depth review of safety shields, including their own ballistics tests. Results will be shared with us. Reinstatement of mandatory shields appears likely.
In response to a significant array of criminal acts inflicted upon Florida's taxicab industry, a proposed Bill has been introduced into their State Legislature to make Safety Shields and Drop Safes mandatory. Debate and decision to come, but appear likely.
9. Other Canadian Jurisdictions
It is not known how many other Canadian jurisdictions, other than Toronto and Winnipeg, are focusing on taxi driver safety to the same degree. To facilitate an exchange of this kind of information, Mr. Doug Cameron, Legal Counsel for the Licencing Division of the Ottawa-Carleton Municipal District has taken the initiative to provoke the formation of a Canadian Association of Taxi Regulators, with a high probability it will emerge in early 1990.
Knowledge of the activities and concerns of the above jurisdictions emerged from out of only 7 weeks review of this high complex issue. It is highly probable that continuing inquiries will reveal a substantially greater number with similar concerns and activities.
The Task Force makes no apologies for clearly primitive research. In the absence of anything better, they believe the critical issue is simply to save lives. No acceptable statistical death rates can be hung on this issue, and every effort must be made to make a taxi driver's workplace as safe as possible.
Following is a set of requirements developed from the "ideal" viewpoint of what shields should accomplish. They are currently in the hands of Winnipeg's Taxi Driver Safety Committee, and a number of manufacturers, and have been favourably received. It is likely that a single shield may not be possible to satisfy all these requirements, but it can come close and provide reasonable protection to the driver, and be reasonably safe for the rear seat passenger.
Taxi drivers face a number of risk areas, and shields by themselves will not provide the answer nor be the elusive panacea. Shields will provide reasonable protection against an initial assault from the rear seat. However, they are not flawless nor infallible. Some perceived weaknesses:
True, this is a known weakness, and a common method of dealing with it is electric door windows. The switch in the rear seat is disabled, so that full control over rear windows rests with the driver only, through his own switch pad controlling all door windows.
To a degree, this is true. Slider type shields restrict air flow the greatest, while vertical retractable shields the least. The heat transfer problem is most commonly solved by the addition of an electric under-seat heater. Improved flow of cool air in summer is being reviewed.
Many new cars are coming equipped with rear set heat/cooling vents. With such vehicles, this weakness is no longer a problem.
True, it is highly probable to a determined assailant, a weapon can be found somewhere that will penetrate a shield. To build a shield that will stop everything would emerge as a formidable barrier, inches thick, with lots of steel. The most significant firearms risk is believed to be small handguns, such as a .38 Special. Most shields will provide good protection from such a weapon, and for the others, will likely deflect the bullet from its intended path. If actual penetration did occur, the bullet would in all likelihood emerge injurious, but non-lethal.
In hopes of determining an approximation of the kind of firearms that a taxi driver may one day face, the Winnipeg City Police, the Chief Provincial Firearms Officer, and the RCMP both local and Ottawa were all contacted. All knew how many firearms are registered, but none could tell us the most frequent caliber weapon that might emerge. All that came forth were personal guesstimates ranging from small .22 pistols, to sawed-off shotguns. No reliable information was available.
Therefore, for the purposes of standards setting, a presumption has been made that our shields should provide Level 2A ballistics protection according to the National Institute of Justice standard 0108.01, low velocity .357 Magnum/9 mm. This is one step higher than the minimum level of protection provided by this standard.
Seat belts have always been mandatory in Manitoba. A rear seat passenger strapped in with a lap belt does indeed risk head contact with the shield. However, the arc of head travel has been determined to impact in the vicinity of the top of the solid lower portion, which is now suitably padded. Rear seat passengers strapped in with 3 point belts have significantly reduced risk of injury for obvious reasons.
U.S. legislation requires 3 point belts in all cars commencing with the 1990 model year. Comparable Canadian legislation is a long way off, likely 1993. However, according to the Road Safety Institute in Ottawa, Canadian manufacturers have voluntarily agreed to install 3 point belts commencing with the 1991 model year.
The taxi driver is required to remind all passengers that seat belts are mandatory in Manitoba. If they fail to buckle up, they do so at their own risk. As an aid to encourage rear seat passengers to buckle up, it would appear highly appropriate to require the following international pictogram be affixed to the rear face of the shield.
The use of safety belts is compulsory in Manitoba
The presumption that the right hand front seat cannot be used is only partially correct. The driver is encouraged to ordinarily keep that door locked from the inside, and only allow a passenger to sit there if he feels comfortable with that fare.
This particular situation, however, is only likely to surface upon a dispatch call where either the pickup or destination point is known, and so recorded. This is ordinarily a lo-risk situation, and a driver may have the discretion to allow that seat to be used. The real risk emerges with "street flags" and the driver would ordinarily exercise caution in any case.
Installation of shields in any car will reduce the available space by approximately 2.5" to 3". In any full size car, this will be negligible, and present rear seat space little or no differently than rear seat space currently available to passengers in intermediate or compact cars now being used as taxicabs.
Our proposed regulation provides for a minimum of 66cm (26") from the face of the rear back rest to the safety shield. By comparison, Air Canada has standard spacing of 29" (74cm) seat-to-seat-to-seat, which coincidentally provides the same 66cm between the face of the back rest to the fold-down tray.
The vertically retractable shield offers the least intrusion to driver/customer communications. When down, normal communications will occur without impediment. However, if the driver perceives a risky situation developing, he can choose to raise the shield immediately. During daylight hours, these occasions of risk would ordinarily be apparent to the driver before the customer enters his vehicle.
A prudent regulatory requirement will put the shield in the upright position after sunset, and it stays up till sunrise. Driver discretion is still available throughout that period, and depending on his level of comfort with his customer, he may choose to lower the shield after the trip is underway.
It has been determined that a 10 year life span may be considered reasonable for an average shield. Most shields encountered in our review were priced well below $1,000 (Can), some as low as $350. Assuming most costly case, $1,000, and a 10 year life, the cost of that shield could be absorbed with a fare increase of .6% to 1.1%. (See attached Appendix A)
The industry periodically tables a submission before the Taxicab Board seeking approval of a fare increase. It would appear quite reasonable that upon next such submission, that portion of such a fare increase applicable to the cost of the shields, could properly be factored into the appropriate formula.
There are 2 basic materials used in various approaches to shield design - steel and LEXAN.
Steel is most frequently used to provide driver protection from the seat top to near floor. It is normally used in the basic design to also house the mechanism for raising or lowering the clear part of the shield, and to affix the assembly to a rigid floor member.
LEXAN is a GE product, a clear polycarbon type of plastic characterized by extreme toughness, and its ability to at very least deflect a bullet. Some are bullet-proof. MARGARD and MARGON are variations of this product with tough skins designed to minimize marring over long periods.
For the purposes of this review, 4 basic types of shield design emerged - traditional police, sliding, retractable, and emergency.
Traditional police type shields, while quite appropriate for their needs, are considered totally inappropriate for taxi needs. They have been designed and built to be truly bullet-proof, to contain a criminal or suspect, and have no requirements to be pleasant. Rear seat passengers in such vehicles are normally secured into place by knowledgeable policemen, and no harm will come to either party. They are ominous, intimidating, and are not recommended for taxi purposes.
Sliding shields are those in which a modest portion of the clear section may be slid to one side to facilitate driver-passenger communications. They are ordinarily left in the open position, but a driver, at his discretion, may choose to close and lock it, depending upon perceived risks. These are typically the least costly shields, but do leave in place, an aura of confinement in the perception of a passenger. While technically acceptable for taxi purposes, this type of shield may be recommended.
A retractable shield is one in which a full width clear polycarbon panel that may be lowered into a bullet-resistant container normally affixed to the floor. It has always been available, but at greater cost. It does provide the least significant barrier to driver-passenger communications, and may be raised at will by the driver depending on his assessment of risk. This type of shield is a reasonable compromise, and may be recommended.
An emergency shield is collapsible steel embedded within the seat itself and ordinarily in the retracted position. It may in an emergency situation be instantly raised by the driver to block an imminent assault. In the upright position, a firm barrier to driver-passenger communications is introduced. While costly, this type of shield may be recommended.
A number of manufacturers were contacted, and some are listed here, but not as a recommendation, only as an indicator. There are certain to be many more manufacturers surface in the foreseeable future in response to normal market and competitive opportunities. This is a healthy situation and one in which the Taxicab Board cannot and will not be a participant.
Over the years, various jurisdictions from time to time, have attempted to resolve the shields issue by mandatory action, similar to our own, that for a variety of reasons failed to actually happen. Consequently, many find it difficult to get interested up front unless we in fact make shields mandatory first. Most wanted firm commitments up front for xxxx shields before they would respond, and preferred to do business directly and only with a single representative of a cab company.
Those that do make shields oriented to taxi cabs, tend to maintain their production facilities by also making and selling shields to police forces. In many cases, the manufacturers clearly were most inclined to do business only in their own local areas, where they and the market were known to each other. Only one manufacturer, Setina, responded positively by designing, building, and bringing one up for demonstration purposes.
The group endeavored to locate a Manitoba manufacturer in a sincere attempt to favour local business. However, manufacturers of safety shields known, or believed to be in this business, are as follows:
It would be inappropriate for the Government to specifically direct that a certain shield be the only shield acceptable, and consequently likely available from a sole supplier. A more appropriate approach is to promulgate approved specifications, appended to an appropriate regulation, and make them available to all Regulators and manufacturers, with the intent of widespread distribution, and fostering a competitive response to the need.
It is true that safety shields have always been permitted, but few have chosen to install them on the perception of competitive disadvantage. Customers have been thought to avoid using a taxicab equipped with a shield. If all cabs were fitted with these shields, then customer choice is perceived to be no longer a negative factor.
The following analysis is based on a single vehicle taxicab operation, but the analysis is equally applicable to each individual vehicle of a taxicab fleet.
The use of a taxicab shield will increase the annual cost of operating a taxicab in three ways:
A service life of 10 years will result in an additional annual depreciation charge of 100 dollars.
Shield maintenance will therefore result in additional costs of about 80 dollars a year.
The total additional annual cost is estimated at about 330 dollars. The additional meter revenue required to offset this additional cost will depend on the nature of the taxicab operation. If a taxicab is driven only by its owner, the owner requires additional revenue of 330 dollars per year to cover the increased annual cost. If the owner does not drive at all, and shares meter revenues with drivers on a 50/50 basis, the required additional revenue is 660 dollars per year.
Data collected by the Board indicates that 60,000 dollars is a reasonable estimate of the annual meter revenue earned by each taxicab. For a taxicab operation in which only the owner drives, an increase in fares of .55 percent will be sufficient to cover the increased costs of a shield; for an operation in which only hired drivers are used, a fare increase of 1.1 percent will be sufficient.
For an operation in which the driving is done partly by the owner and partly by hired drivers, an increase in fares of between .55 percent and 1.1 percent will be required, depending on how much of the driving is done by hired drivers with whom revenue must be shared. The required fare increase rises as the proportion of hired driver time rises.
Since fares must be increased uniformly for all taxicab operations, an increase of 1.1 percent will be adequate to ensure that all taxicab operations are able to cover the costs of shields.
To review various taxicab safety devices, tools, techniques, etc., to enhance the safety of a taxi driver's workplace.

National Institute of Justice
This document, N1J Standard-0108.01, Ballistic Resistant Protective Materials, is an equipment standard developed by the Law Enforcement Standards Laboratory of the National Bureau of Standards. It is produced as part of the Technology Assessment Program of the National Institute of Justice. A brief description of the program appears on the inside front cover.
This standard is a technical document that specifies performance and other requirements equipment should meet to satisfy the needs of criminal justice agencies for high quality service. Purchasers can use the test methods described in this standard to determine whether a particular piece of equipment meets the essential requirements, or they may have the tests conducted on their behalf by a qualified testing laboratory. Procurement officials may also refer to this standard in their purchasing documents and require that equipment offered for purchase meet the requirements. Compliance with the requirements of the standard may be attested to by an independent laboratory or guaranteed by the vendor.
Because this NIJ standard is designed as a procurement aid, it is necessarily highly technical. For those who seek general guidance concerning the selection and application of law enforcement equipment, user guides have also been published. The guides explain in nontechnical language how to select equipment capable of the performance required by an agency.
NIJ standards are subjected to continuing review. Technical comments and recommended revisions are welcome. Please send suggestions to the Program Manager for Standards, National Institute of Justice, U.S. Department of Justice, Washington, DC 20531.
Before citing this or any other NIJ standard in a contract document, users should verify that the most recent edition of the standard is used. Write to: Chief, Law Enforcement Standards Laboratory, National Bureau of Standards, Gaithersburg, MD 20899.
The purpose of this standard is to establish minimum performance requirements and methods of test for ballistic resistant protective materials. This standard supersedes NIJ Standard-0108.00, Ballistic Resistant Protective Materials, dated December 1981. This revision adds threat level III-A and establishes threat level classifications that are consistent with other NIJ standards for ballistic protection.
This standard is applicable to all ballistic resistant materials (armor) intended to provide protection against gunfire, with the exception of police body armor and ballistic helmets, which are the topic of individual NIJ performance standards [1,2]. Many different types of armor are now available that range in ballistic resistance from those designed to protect against small caliber handguns to those designed to protect against high- powered rifles. Ballistic resistant materials are used to fabricate portable ballistic shields, such as a ballistic clipboard for use by a police officer, to provide ballistic protection for fixed structures such as critical control rooms or guard stations, and to provide ballistic protection for the occupants of vehicles. The ballistic resistant materials used to fabricate armor include metals, ceramics, transparent glazing, fabric, and fabric-reinforced plastics; they are used separately or in combination, depending upon the intended threat protection.
The ballistic threat posed by a bullet depends, among other things, on its composition, shape, caliber, mass, and impact velocity. Because of the wide variety of cartridges available in a given caliber, and because of the existence of hand loads, armors that will defeat a standard test round may not defeat other loadings in the same caliber. For example, an armor that prevents penetration by a 357 Magnum test round may or may not defeat a 357 Magnum round with higher velocity. Similarly, for identical striking velocities, nondeforming or armor-piercing rounds pose a significantly greater penetration threat than an equivalent lead core round of the same caliber. The test ammunitions specified in this standard represent common threats to the Iaw enforcement community.

Examine the witness plate to determine penetration, and examine the specimen to see if the bullet made a fair hit.
If no penetration occurred, reposition the test specimen and repeat the procedure with additional test rounds until the test is completed. Space the hits as evenly as possible so that every portion of the test specimen is subject to lest.
(This Foreword is not part of American National Standard Z26.1-1983.)
The American Standard Safety Code, Z26.1 ·1938, was developed by a sectional committee, national in scope, functioning under the procedure of the American Standards Association and under the joint sponsorship of the National Bureau of Casualty and Surety Underwriters (now the American Insurance Association) and the National Bureau of Standards. lt was the first of several separate codes to be developed within the scope of Standards Committee Z26 on Specifications and Methods of Test for Safety Glazing Materials. That scope is as follows:
Specifications and methods of test for safety glazing material (glazing material designed to promote safety and reduce or minimize the likelihood of personal injury from flying glazing material when the glazing material is broken) as used for windshields, windows. and partitions of land and marine vehicles and aircraft.
Since the original formulation of the American National Safety Code, Z26.1-1938, the development of synthetic plastic materials has so far advanced that a number of them appcar to be practical for certain uses as safety glazing materials for glazing motor vehicles operating on land highways; therefore, in the 1966 edition of this standard, both the foreword and code were modified to the extent necessary to include these synthetic plastic materials along with glass under the general term of "safety glazing materials" reserving the use of the word "glass" as applying only to the ceramic material, and of the word "plastic" as applying only to synthetic, organic, plastic materials.
Early in its deliberations, the Z26 Committee recognized the fact that no one set of specifications or methods of test could well apply to safety glazing materials as used for all purposes. Therefore, the members decided to prepare a separate code for each of the major usages included in the scope of the main project. In keeping with that decision, this code, as its title indicates, pertains only to "Safety Glazing Materials for Glazing Motor Vehicles Operating on Land Highways."
It is hoped that the test procedures and performance requirements detailed in this standard may be uniformly adopted by motor vehicle commissioners and other interested regulatory officials as the basis for their approval of the safety glazing materials in motor vehicles coming within their jurisdiction, or for incorporation in their regulations; that they may serve as a guide to automobile manufacturers as to the safety glazing materials which will be acceptable to such officials; and that they may enable the consumer (the commercial operator and the general public) to have assurance that the safety glazing materials in the motor vehicle that is purchased should reduce, in comparison with glass of ordinary types, the likelihood of injury to persons riding in such motor vehicles by these safety glazing materials whether they may be broken or unbroken.
It is the fundamental purpose of this standard to prescribe the functional properties of safety glazing materials in such a manner that they can be used in any place in the motor vehicle for which they possess those mechanical, or optical properties, or both, that are requisite and appropriate. For example, safety glazing materials for windshields must pass a specified group of test requirements, all of which currently can be met only by certain laminated safety glass; however, if and when other safety glazing materials are developed that possess properties such that they, too, fulfill the requirements of the prescribed tests for this location, they may also be used; and similar reasoning would apply for other locations. This standard is designed to serve two purposes: (1 ) to afford a basis for standards for adoption in regulations by governmental regulatory bodies; or (2) for use by motor vehicle commissioners or others as reference standards in such cases as they may have discretionary authority to adopt these or other standards in connection with the approval of safety glazing materials or other items of use in or on a motor vehicle.
This standard does not state that safety glazings shall be used or to what extent they shall be used in glazing motor vehicles. Such requirements rest with either the legislative or administrative authority. When by law or regulation escape or emergency egress openings are required and when such requirement is met by use of glazed openings, Test 25 (see 5.25) is provided as a means of measuring and establishing the escape value of the safety glazing material.
This standard, which is the result of extended and careful consideration of available knowledge and experience on the subject, is intended to provide minimum requirements that are recommended for use, adoption, and enforcement by federal, state, and local administrative authorities. It is recommended that this standard should not be incorporated in any statute.
Caution should be exercised not to make laws and regulations dealing with this subject so inflexible as to preclude subsequent adoption of technological advancements in the development of safety glazing materials.
Except for special requirements for specified locations, safety glazing materials of six general types can meet some or all requirements detailed in this standard. All six types are commercially available today. Each of them possesses its own distinctive safety characteristics. The six types may be briefly described as follows:
(1) Laminated Glass. This consists of two or more pieces of sheet, plate, or float glass bonded together by an intervening layer or layers of plastic material. It will crack or break under sufficient impact, but the pieces of glass tend to adhere to the plastic. If a hole is produced, the edges are likely to be less jagged than would be the case with ordi- nary annealed glass.
(2) Tempered Glass. (Other terms such as "heat treated glass," "heat toughened glass," "case hardened glass," and "chemically tempered glass" are used also.) This consists of a single piece of specially treated sheet, plate, or float glass possessing mechanical strength substantially higher than annealed glass. When broken at any point, the entire piece breaks into small pieces that have relatively dull edges as compared to those of broken pieces of ordinary annealed glass.
(3) Wire Glass, This consists of a single piece of glass with a layer of meshed wire completely imbedded in the glass but not necessarily in the center of the glass.
(4) Plastic. A plastic is a material that contains as an essential ingredient one or more organic polymeric substances of large molecular weight, is solid in its finished state, and, at some stage in its manufacture or processing into finished articles, can be shaped by flow.
(5) Multiple Glazed Unit. This consist of two or more sheets of glazing material separated by an airspace or spaces and glazed in a common mounting. For the purposes of this standard, multiple glazed units are divided into two classes:
(a) Class 1 comprises multiple glazed units in which each component single layer or laminated layer complies with the appropriate requirements of this standard.
(b) Class 2 comprises multiple glazed units in which any component single layer or laminated layer does not comply with the appropriate requirements of this standard.
(6) Bullet Resisting Glaring. This consists of one or more layers of glass bonded together with one or more layers of transparent plastic or of transparent plastic material solid or laminated, that can meet the bullet-resisting requirements of this standard.
The Z26 Committee and the Secretariat believe that this standard reflects the best current technology in the art of automotive glazing. It is recognized that new developments are to be expected in safety glazing materials, and that revisions of the standard will be necessary as the art progresses and as further experience is gained. It is felt, however, that uniform requirements are very much needed, that the standard in its present form permits the use of the more desirable types of safety glazing materials now commercially available, and that it distinguishes between the better and the poorer grades of those types, as well as prescribing and, in some cases, limiting the places at which certain types may be used.
The 1983 revision of the standard recognizes a new class of glazing materials, Glass-Plastic Laminated Glazing (Item 1 A). The tests to define the characteristics of such glazing as suitable for windshield use address all of the requirements of conventional laminated glass windshields. Special attention is given to the inner plastic surface to ensure that durability is adequate to meet the requirements of driver visibility. For this, tests for weathering, chemical resistance, and abrasion resistance have been added. Footnotes to this standard are included for purposes of clarification and are not part of American National Standard Z26.1-1983.
Suggestions for improvement of this standard will be welcome. They should be sent to Society of Automotive Engineers, Inc, 3001 West Big Beaver, Troy, MI 48084. This standard was processed and approved for submittal to ANSI by American National Standards Committee on Specifications and Methods of Test for Safety Glazing Material, Z26. Committee approval of the standard does not necessarily imply that all committee members voted for its approval.
