Protect against blasts, as tested to the glass standard EN 13541 for resistance classes ER1 through ER4 (S/NS) and system standard EN 13123-1 and 13123-2.
Blast proof glass also known as explosion proof glass is designed to achieve an ideal combination of stiffness and compressive strength of glass with the plasticity and energy-absorbing properties of polymer interlayers such as PVB. The designation Classes ER1, ER2, ER3, or ER4 depends on the corresponding amount of explosive pressure it is tested to withstand during simulations of an explosive detonation in a controlled shock-tube test mechanism. After testing, the high security glass should remain in the test frame to prevent fragments from harming people on the protected side. Blast proof glass can be classified as splintering or non-splintering. The non-splintering option means that, even in the event of an attack, there is less risk of injury to those in the immediate vicinity if the glass is broken: it does not splinter into sharp fragments but remains bonded to the interlayer. If there is no danger of injury to those nearby, the splintering option is a cost-effective alternative.

A shock wave from an explosion can transform standard glass into deadly projectiles. Blast proof glass is designed to be flexible. It remains in its tested frame by absorbing the force of blast waves according to its specific blast resistance classification.
