Burglar resistance

The pre-standard ENV 1627: 1999 applied until 2011, which has since been replaced by the Euro standard EN 1627: 2011. The standard applies to doors, windows, curtain walls and closures and defines resistance classes, resistance times (time a product can withstand a break-in), types of perpetrators and the procedure. Since September 2011, the resistance classes are no longer designated with WK (resistance class), but with “RC” for “resistance class”. The resistance classes RC1N and RC2N, which can only be implemented with standard window glass, have been newly introduced. Lock and fitting) are no weak points.

Resistance class Glazing
DIN EN 356
Type of attack / weapon Manual test time DIN V EN 1630
RC1 / WK1 Laminated safety glass Basic protection against physical violence / vandalism: kicking, pushing, jumping. Little protection against lever tools -
RC2 / WK2 P4 A Protection against physical violence and simple tools such as screwdrivers, wedges, pliers, jigsaws, hacksaws or hacksaws 3 - 15 min
RC3 / WK3 P5 A

Additionally: hand drill, engineer's hammer, screwdriver and goat foot

5 - 20 min
RC4 / WK4 P6 B

Additional use of sawing and striking tools such as ax, chisel, hammer, bolt cutter, tin snips, chisel, cordless drill

10 - 30 min
RC5 / WK5 P7 B

Experienced perpetrator: Additional use of power tools such as a drill, jigsaw or reciprocating saw and angle grinder

15 - 40 min
RC6 / WK6 P8 B

Experienced perpetrator: Additional use of even more powerful power tools

20 - 50 min

When calling for burglar resistance, please note:

Armored glass is not tested according to the standard for burglar resistance according to DIN EN 1627 - glazing is tested according to DIN EN 356 according to the so-called break-through resistance.

In case of break-through resistance, an ax is used to test whether there is a perpetrator (within a period of time specified by the standard) it is possible to create an opening the size of 40 x 40 cm through which he can enter the building.

There is a discrepancy between the two standards when burglar resistance and break-through resistance are mixed together, as is the case with glazed doors and windows

When testing burglar-resistant doors and windows in the high steps RC5 and RC6 (WK 5, WK6) an angle grinder is also used in the tests, but not when testing the glass for breakthrough resistance.

With an angle grinder, an opening can be flexed out of bulletproof glass in a few minutes through which a thief can get in.

So if glazed doors and windows are to be supplied with burglar resistance RC5 and RC6, normal glazing is an absolute weak point that does not meet the requirement for burglar resistance at this level.

Even with the lower classes there is a weak point with regard to the burglary protection with normal glazed elements:

The burglary test always assumes that you have an opening g (40 x 40 cm) to penetrate the building. In the case of doors, however, it is much quicker to knock a small opening in the glass in order to reach through with a tool or the hand and to operate the handle, key, knob on the inside of the door Burglar-resistant sash windows and glazed doors can be equipped with lockable handles.

Doors must always be locked and the key must not be on the inside.

A locked door also helps with burglar-resistant doors with an escape route and panic function Do not, because the door handle always has to open the locked door lock. In the case of doors with a panic function, normal glazing is therefore not sufficient in accordance with the required test class, as the door handle can be easily operated through a hole in the glazing. (see photo) - The door opens - the resistance class is not reached.

Escape and panic doors therefore require special glass (polycarbonate glass composite) to prevent such attacks.

The EN 1627 standard describes the attack on the construction and the associated components, but not the direct attack on the glass. The subsequent norms 1628-static load, 1629-dynamic load and 1630-manual test supplement the EN 1627 in this regard. In the norm 1630 the manual attack on the glass is specified. The individual tool sets - A1 to A6 - are to be used as described in the standard. The attack times are also specified there.

Contact us and let's find the right product for your needs together.

Important: A polycarbonate pane that is placed loosely behind a glass pane does not meet the requirements. The two panes (polycarbonate and glass) must be connected to one another in a special process. This is the only way to reach the resistance classes.
