Burglar resistance

When determining the burglar-resistant properties, these are divided into six classes, the so-called resistance classes (RC = Resistance Class). Resistance class RC 1 (N) corresponds to the lowest level of protection and resistance class RC 6 to the highest.

In Germany, class RC 2 is regarded as the “standard protection level” for flats and private houses with good burglar-resistant properties.

Class RC 3 is seen in Germany as a “protection level with increased requirements” for secluded private houses and properties, but also for locations with increased risk.

Building elements with resistance classes RC 4 and higher are in many cases special solutions that take special hazards into account.

Together with PfB you can prove burglar resistance in all resistance classes.

With the 2021-11 edition, the DIN EN 1627 to DIN EN 1630 series of standards has been reissued. Of course, there have also been some changes in this series of standards. We have summarised the most important points for you:

When testing the burglar-resistant properties, the entire building element including the assembly in the building structure is to be considered. This is a destructive test in which representative test samples are subjected to the loads of the resistance class to be achieved.

If desired, the test can also be carried out on site, at the manufacturer’s or at the construction site.

The test is divided into three areas:


  • Resistance under static load
    (static test – pressure stamp)
  • Resistance under dynamic load
    (dynamic test – pendulum)
  • Resistance to manual break-in attempts
    (manual test – tools)

Depending on the resistance class, the static load, the drop height of the pendulum or the tool selection and the resistance time for the building element change.


Burglar-resistant retrofit products


Burglar-resistant retrofit products are divided into two categories according to the way they are installed:

  • screw-on retrofit products – which are subsequently screwed onto a window or door or onto the adjoining wall and improve the burglar-resistant effect of the building element
  • Retrofit products recessed in the rebate – which are subsequently recessed in the rebate of windows or doors and improve the burglar-resistant effect of the building element.


In addition to the test, the comprehensibility of the installation instructions is also assessed.

Construction elements / standards

The following construction elements can be tested and classified:
