Resistance classes

The resistance classes are marked with the abbreviation "RC" according to DIN EN 1627.
There are 7 resistance classes defined according to DIN EN 1627: RC 1 N, RC 2 N, RC 2, RC 3, RC 4, RC 5, RC 6.

DIN EN 1627 defines 4 product groups. Components are assigned to these groups according to their technical and structural properties and their specific function.

Examples:

  • group 1: tilt and turn windows, doors
  • group 2: sliding windows and sliding doors
  • group 3: roller shutters
  • group 4: grid elements (fixed / movable)

The 7 resistance classes

  • WK = resistance class according to DIN V ENV 1627:2011
  • WK (old) = resistance class according to DIN V ENV 1627:1999
  • WZ = resistance time
WK WK (old) WZ Perpetrator type / approach
RC 1N 1) WK 1 none Attempted break-in with physical force such as kicking, jumping against, pushing up or similar. The windows have only very low burglary protection.
RC 2N 1) WK 2 3 min The opportunist also tries to break open the window with simple tools such as screwdrivers, pliers and wedges, pliers and wedges to break open the window. The windows have a low average burglary protection.
RC 2 WK 2 3 min The opportunist also tries to break open the window with simple tools such as screwdrivers, pliers and wedges, pliers and wedges to break open the window. The windows have a low average burglary protection.

1) The suffix "N" for the resistance classes "RC 1 N" and "RC 2 N" stands for "normal" and means, and means that normal glass without attack-resistant properties can be used here.
