Australian and New Zealand Standard - Bullet Resistance Panels and Elements

The primary function of bullet resistant panels and elements is to prevent penetration by projectiles discharged from firearms. Protection from any particles of the panels and elements under attack (such as glass splinters or metal particles) is also desirable and such performance is required for compliance with this standard.

 

As the nature of fitting and method installation of glazed or opaque panels and elements may be widely varied, it is not possible to specify instructions for installation within this standard. However, it must be noted that the degree of protection depends as much on the design, fixing and maintenance of the panel and element as it does upon the bullet resistant panel or element itself. Accordingly, the frames or surrounding areas of the panels elements should provide as high level of protection as the panels and elements themselves and any support system should also provide sufficient overlap to prevent dislodgment of the panels when under attack. The panels and elements must be correctly installed according to their design characteristics, particularly important in relation to specific mounting or glazing requirements, or where necessary to orientate the bullet resistant panels or elements in relation to the expected direction of attack.

 

Where any doubt exists regarding installation of bullet resistant panel and elements, further information should be obtained from the manufacturer.

Scope

This standard specifies requirements for bullet-resistant panels and elements according to their performance in preventing penetration by projectiles from firearms under controlled conditions. This standard applies to transparent, opaque and translucent panels and other components including but not restricted to frames, mullions, voice transfer louvres and pass through devices. (Elements).

 

This standard does not include a requirement for the retention of bullet resistant properties for a stated period of time nor requirements for certain other aspects such as the durability of the glazing. Such requirements may be nominated by a purchaser who will determine the criteria and agree to the method for demonstration compliance.

    1. Projectile mass shall be within 2% of the nominal mass
    2. If a test satisfies the requirements at velocities greater than the table, it is deemed to pass
    3. Range is the distance from the muzzle to the panel or element.
    4. If a test satisfies the requirements at shot centres less than minimum, it is deemed to pass.
    5. For other elements see Clause 6.2.3.
    6. Special class covers protection other than the preceding classes. Calibre, ammunition and other details shall be specified by the user or manufacture as appropriate.
