Explosion tested safety glass
In a powerful explosion, conventional glass panes will splinter even at a great distance from the explosion, often with serious splinter injuries as a consequence. In properties located in the immediate vicinity of the explosion even splinter-free panes will be forced in, despite being made from toughened or laminated glass. Hammerglass explosion resistant solutions will hold the panes firmly in position even in a powerful explosion.
A series of tests in accordance with EN 13124-2 has been conducted on Hammerglass screens. A number of explosions were carried out, at varying distances from the Hammerglass screen. As a result it was demonstrated that 12 mm Hammerglass screens withstand the pressure wave generated by 3 kg TNT being exploded at a distance of 3 metres.
