Depending on the type of weapon and calibre and the way in which the shelling test is to be carried out, the Euro standard subdivides into seven different classes of shelling. When testing glazing, the test results are given the addition “S” for splinter outlet or “NS” which means “non-splitting. ”
It’s a safe thing from penetration. SITEC offers bulletproof systems up to the highest resistance class FB7. We make sure that the individual components fit perfectly together so that the complete system meets the safety regulations.
