The bulletproof classifications

The bulletproof classifications in accordance with

Euro Standard EN 1522

have applied since the end of 1998.

Until now, nearly every European country had its own bulletproof classifications with different tests conditions.

The new Euro Standard EN 1522 now applies all over Europe and replaces all bulletproof standards that have applied in these countries until now.

The new Euro Standard applies to all bulletproof doors, windows, shutters, transfer trays and all other bulletproof materials. Euro Standard EN 1522 also requires that any glass incorporated into structures be tested in accordance with the corresponding Euro Standard EN 1063.

Besides type of weapon and calibre, the new Euro Standard also defines the manner in which tests have to be carried out.

Instead of the five previous bulletproof classifications (Material: M1 to M5 – Glass: C1 to C5), there are now seven bulletproof classifications (Material: FB1 to FB7 – Glass: BR1 to BR7).

In addition, there is a new resistance classification for rifles (Material: FSG – Glass: SG2).

A key point during all testing is whether material or glass on the inside of the part splinters off.

For this reason the test results get the additional remark:	S = splinters
	NS = shatterproof

The table below compares the bulletproof classification DIN 52 290 that was previously valid in Germany with the new Euro Standard EN 1522.

This comparison, however, is misleading.
Our tests proved:
A 12 mm thick steel plate stood up to an M4 test in accordance with DIN 52290, whereas it was shot through during an FB6 test in accordance with Euro Standard EN 1522.

Bulletproof glass in accordance with DIN 52 290 stood up to a C4 test in accordance with DIN 52290, whereas it was shot through during a BR6 test in accordance with EURO Standard EN 1063.

Nearly all SITEC products, doors and partition walls have meanwhile been adapted and technically tested to the much higher requirements of the new EURO Standard EN 1522.

*	In order to meet the requirements for calibre (5.56 x 45), a range of (178 ± 10 mm) is recommended
**	In order to meet the requirements of class FB 7, a range of (254 ± 10 mm) is recommended
	Note 1:If only one shot is fired, the test distance can be reduced, in order to achieve the accuracy required by EN 1523 : 1998, section 6. In this case it may not be possible to measure the firing speed. Note 2: In order to be classified FB 4 or FB 6, the material has to be tested with both of the above mentioned types of weapon.
