Use of Descriptive Terms. As the definition indicates, safety glazing materials, in comparison with ordinary sheet glass, plate glass, or float glass, are intended to reduce the likelihood of injury or the severity of injury in the event of their breakage. Therefore, terms such as "non breakable," "non scatter able", "non splinter able" should not be interpreted by the driving public as meaning that absolute protection is afforded to the occupants of the vehicle by the safety glazing materials so described, as the descriptive terms might seem to warrant. No such terms are used in this standard.
Bullet-resisting glazing should not be termed "bullet-proof', since no bullet-resisting glazing is completely resistant to penetration by all types of missiles fired from all types of armament.
Degree of Safety. One safety glazing material may be superior for protection against one type of hazard, whereas another may be superior against another type. Since accident conditions are not standardized, no one type of safety glazing material can be shown to possess the maximum degree of safety under all conditions, against all conceivable hazards.
Purpose of Tests. The tests described in this standard are for the purpose of determining whether a safety glazing material has certain desirable and obtainable qualities for its acceptance under this code. Many of the tests are of such severity that even a satisfactory product will show occasional failures to an extent limited by the requirements of the test.
