Over deze norm
1.1 This specification covers glazing, glazed windows, glazed curtain walls, glazing panels in doors, other glazed protective systems, and non-attached window retrofit systems used in buildings that may be subjected to intentional or accidental explosions.
1.2 This specification addresses only glazing, glazing systems, and glazing retrofit systems. This specification does not address the structural integrity and functionality of door assemblies. It assumes that the designer has verified that other structural elements have been adequately designed or tested to resist the anticipated airblast loads.
1.3 This specification is designed for all glazing, glazing systems, and glazing retrofit systems including, but not limited to, those fabricated from glass, plastic, glass-clad plastics, laminated glass, glass/plastic glazing materials, organic coated glass (filmed), and non-attached glazing retrofit systems such as blast curtains, cables, shades, and architectural mesh.
1.4 This specification does not determine the assessment of a facility nor acceptable hazard ratings. Threat and risk assessment shall have already been performed and the acceptable hazard rating defined. The hazard rating should be selected taking into account the installed position of the glazing. Glazing at higher elevations relative to the floor may require more stringent hazard considerations.
1.5 This specification determines the hazard rating associated with blast tested glazing, glazing systems, and non-attached glazing retrofit systems. In addition to glazing fragments and system components creating hazards, glazing slivers are also included as part of the hazard rating. The inclusion of slivers may cause a worse hazard rating than is predicted when using analytical approaches such as presented in Practice or in other methods.
1.6 The values stated in SI units are to be regarded as the standard. Values given in parentheses are for information only. For conversion of quantities in various systems of measurements to SI units, see .
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
