Specification for impact performance requirements for flat safety glass and safety plastics for use in buildings
Executive summaryImpact performance requirements and test method for flat safety glass and safety plastics for use in buildings.
AbstractThis British Standard specifies performance requirements and a test method in respect of energy absorption (impact) for flat safety glass and safety plastics for use in buildings. These requirements are intended to reduce the risk of injuries caused by cutting and piercing in accidents where these materials are involved.
This standard does not specify situations where safety glass and safety plastics should be used, nor does it specify requirements for their durability.
The concept of safety in this standard relates to a given level of impact energy and to a requirement for the glass and plastics: break safe or no break. They are developed following very extensive observation of available materials breaking under the test conditions and following the use of different impact energies to test materials having different levels of mechanical strength.
History and related standardsThis British Standard includes the following cross-references:
BS-4, BS 4-1 and CP 152.
