All about glass > SG & SGNS Bullet Resistant Glass Classification

Our Bullet resistant Plastofloat is tested and rated according to European standard EN 1063 specifications SG1 or SG2
based on its ability to withstand shotgun attacks, not just by stopping the bullets, but also in terms of the spall ejected
on the opposite face.
To be rated SG , the glass must withstand a shotgun round without being perforated. The test is always performed
successively on three samples of the same glass. The resistance level is determined by the number of impacts.
