Performance requirements and procedures for type testing for glazing resistant to five levels of attack by hand-held guns firing bullets and one level of attack by shotgun. For use at temperatures between 10°C and 30°C. Essential information for installation is also given.

1.1 This Part of BS 5051 specifies performance requirements and type test methods for six classes of bullet-resistant glazing for interior use, designed to resist attack by handguns, rifles and shotguns. It covers glazing for use at temperatures between 10 °C and 30 °C.

NOTE Glazing resistant to manual attack (anti-bandit glazing) is covered in BS 5544. However, glazing complying with this Part of BS 5051 may also be highly resistant to many forms of manual attack.

1.2 This Part of BS 5051 does not include requirements for freedom from visible defects or for light transmission. It does not specify requirements for the retention of bullet-resistant qualities over a stated period (but see 0.3).

NOTE 1 Under conditions where bullet-resistant glass may be subjected to abrasion, unsatisfactory methods of cleaning or excessive ultraviolet light, bullet resistant qualities may be impaired. Additional requirements should therefore be agreed between the purchaser and the vendor.

NOTE 2 Panels of bullet-resistant glass much smaller than the test piece specified (see 4.1) may provide less protection in service than would be indicated by the performance of the test piece. Additional requirements should therefore be agreed between the purchaser and the vendor.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.
