The EN 356 standard defines six resistance classes. RC1 windows provide the least resistance, while TC6 windows provide the highest resistance.
are tested against physical force impacts: Against kicking or jumping, lifting, ripping out. No tools are used - and even unpracticed amateur thieves use tools.
withstand an amateur culprit with a simple tool for about three minutes. The glass is ignored during the test! Only P4A glass is specified and that is destroyed already after a few seconds. SILATEC P6B glass in contrast withstand for five minutes.
This is where the test engineer attacks as a practiced culprit, with crowbar or chisel, and the window must withstand the attack for five minutes. The glass will not be tested! Only P5A glass is specified, however, it is broken after 15 seconds. A decision for SILATEC P6B glass with also five minutes resistance time seems to be significantly more rational.
must withstand for ten minutes against an experienced culprit with a saw, striking tool and power drill. The glass is not attacked, only any P6B glass is listed as a reference. 30 seconds and it is destroyed! Recommendation: SILATEC P8B glass with approx. twenty minutes resistance time.
last 15 minutes against an experienced culprit with electrical tools (power drill, jigsaw or saber saw, angle grinder). Despite the fact that the glass is tested here, only common P7B glass is recommended: it is broken in less than one minute. Recommendation: SILATEC P8B glass. About twenty minutes resistance.
20 minutes resistance, experienced culprit with powerful electrical tools (power drill, jigsaw or saber saw, angle grinder). The glass will be tested. It is unintelligible that the recommendation is for P8B glass: it is broken after about one minute. Our recommendation also here: SILATEC P8B with approx. twenty minutes.
