In order to determine the degree of protection against burglary, resistance categories were created (in accordance with European norm ENV 1627-1630). This classification is based on perpetrator type, behaviour, area of application, risk and application recommendation. There are six classes of resistance.
- In RC 1 building components provide basic protection against burglary attempts using physical violence (kicking, jumping, shoving, pushing up, yanking away, etc.). These building components do not provide a lot of protection against the use of crowbars.
- In RC 2 the impulse thief tries to break into the closed and locked building component using simple tools (screwdrivers and pliers).
- In RC 3 the perpetrator tries to break into the closed and locked building component using a second tool (crowbar or cordless drill).
- In RC 4 we are dealing with a professional thief who carries additional sawing and percussion tools (gouge, chisel, hammer, etc.) in order to break into the building component.
- In RC 5 and 6 the burglar uses further tools such as a grinding disc, electric drill and sledge hammer.
All Reynaers systems at the very least satisfy the legal requirements for resistance class 2.
