This standard gives specifies the requirements and test methods for durability, strength, security and function of mechanically operated locks and latches for use in doors. Window doors and entrance doors in buildings.

Test Summary

The standard cover the classification of locks and latches for use with different types and categories of doors used in buildings. Many different tests are described including the torque to turn keys, the force necessary to close and resistance to side load on the latch or dead-bolt. Mecmesin can offer torque and force measuring instruments and bespoke fixturing to perform most of the tests in this standard.

Test Apparatus

The standard can be applied to many different locks and latches ranging widely in their use and duty requirements. Suitable bespoke fixturing will need to be considered for each of the tests and the locks to be tested.


Refer to the standard and the required annexes for details of the test to be performed and apparatus involved.
