DIN EN 1627:2011: Classification of burglar-resistant constructions considering market requirements.
European requirements for burglar-resistant structures: windows, doors, facades, grilles, and shutters; in accordance with the DIN EN 1627:2011 standard.
In September 2011, the European standard DIN EN 1627:2011 was adopted, setting out burglary resistance requirements for door sets, windows, curtain walling, grilles, and shutters. It replaced DIN V ENV 1627, which had been in effect since 1999 and applied only to windows, doors, and shutters.
The abbreviation DIN EN indicates that this document is a German edition of a European standard, adopted without changes across the European Union.
It applies to fixed or static structures, as well as the following types of openings: rotation, tilt, folding, swing, pivot and tilt, swinging, horizontal and vertical sliding, upward and downward movement, as well as rolling.
Features of the DIN EN 1627:2011 Standard
While ENV 1627 did not differentiate between products (only roller shutters were considered separately), EN 1627 defines four product groups based on their construction:
- Turn-tilt windows and doors.
- Sliding windows and doors.
- Shutters.
- Grilles (fixed and mobile).
Previously, burglary resistance classes were designated by the abbreviation WK (Widerstandsklasse, meaning "resistance class" in German). The new standard introduced the RC (resistance class) designation. Additionally, two new classes were added: RC1N and RC2N, where "N" denotes structures with standard glazing.

Differences Between RC and WK Resistance Classes
Comparing the resistance classes of the new standard with its predecessor, only minimal changes were introduced in practice.

No correlation due to changed testing requirements. |

WK2 + glazing is chosen at the discretion of the customer unless specified otherwise in the project specifications. |
