DG Special Glass has the experience to provide solutions for blast resistant glass and blast resistant windows or doors. Blast resistant glass has a similar structure to bulletproof glass and attack resistant glass, but with better performance, higher quality and tougher materials are used to achieve higher blast resistance.
The purpose of blast resistant glass is to reduce the risk of injury to building occupants from blast shockwaves or glass fragments. The performance of blast resistant glass must be verified by test evidence. The first step in design is to determine the blast load. This is best specified as the blast pressure and pulse.

Blast Resistant Glass Standard
EN 13541:2012 This European Standard specifies test methods, performance requirements and classification of blast resistant pressure glass for use in buildings. The protection provided by blast resistant glazing depends not only on the product itself, but also on the design and fixing of the glass. It is not permitted to have any holes in the glass or between the glass and the frame (breakthrough from the attack to the protective surface). It is permissible to award an additional Shatter (S) or No Shatter (NS) designation. Fragmentation is defined as the cracking of the rear surface (protective surface) or the ejection of small fragments (glass powder) from the rear surface.
EN 13124-1:2001 and EN 13124-2:2004 Do not allow any openings that can be penetrated by a stiff rod with a diameter of 10 millimeters (mm). No part of the frame or gasket may be detached. Fragmentation needs to be recognized and registered as S or NS.
GSA-TS01:2003 The testing is specifically tailored to meet the needs of federal buildings and is based on real-world explosive scenarios (such as bomb threats, terrorism, etc.). The testing procedures and performance standards align directly with the security needs of government buildings.The United Kingdom (UK) hazard ratings are used, with minor modifications. The rating system is based on projecting glass fragments into a 3-meter deep compartment.
In ISO 16933:2007 and ISO 16934:2007 This International Standard provides a structured procedure for determining the air air-blast resistance of glazing, incorporating seven standard explosions simulating car bombs and seven standard explosions simulating small sidearm bombs, which can be used to classify glass properties and cover a wide range of blast parameters. More sophisticated hazard criteria were used. Finally, these criteria allow the classification of hazard classes based on observed damage.
