    Glazing manufacturers have been producing attack resistant glass to comply with industry standards for years, some of those listed below are technically no longer current but the products they produced are still in everyday use.

    For many years an industry favorite has been 11.3mm 5ply, this was developed to comply with BS5544: 1978 (1994), which is the UK standard for anti-intruder glazing. Although the standard was developed to represent an attack by a blunt instrument such as a hammer, the test comprises multiple drops of a steel ball from varying heights. The ball must not penetrate the glazing in either test. It is a straight forward pass or fail test and thus gives no indication of the number of blows or the time required to achieve penetration.

    EN 356 is a European Standard for glazing to withstand an intruder attack, it has two resistance levels, the lower levels, P1A - P5A, use the drop test but the higher resistance levels test using a hydraulically driven hammer and axe head, to replicate an actual attack. The higher resistance levels, P6B, P7B and P8B, require the samples to withstand 31-50, 51-70, or 71+ combined sledge hammer and axe blows, before a 400mm square aperture is created.

    LPS 1270 was developed by LPCB to certify glass products to be compatible with LPS 1175. LPS1270 differs from EN356 in that the test is carried out by a person able to vary his choice of tools and method of attack, within the duration of the test. LPCB believe this better represents an actual attack rather than the robotic method used in EN356. The result is to provide a range of tested categories, dependent on the tools allowed and the duration of the test, the higher categories' of which exceed those of EN356.

    Architectural Armour can supply all of the above glass options into a wide variety of glazed security products, please call to discuss your requirements.
