British Standards door security information

  • In all instances it is good practice to fit British Standard (BS) approved locks to all external doors. In many cases this is an insurance company requirement. Our Union BS 5 lever locks carry the BSI Kitemark™ and are approved to either BS 3621: 2007 or BS EN 1303: 2005, rigorous test standards to which the locks must perform.
  • BS 3621: 2007 – A well-established product standard for thief-resistant locks in the UK. Locks tested to BS 3621: 2007 must exceed a minimum level of performance and be subjected to a general vulnerability assessment to enable the product to be Kitemark™ by BSI.
  • BS EN 1303: 2005 – The product standard for thief-resistant cylinders for locks in the UK. Locks tested to BS EN 1303: 2005 must pass various performance and vulnerability assessments to enable the product to be Kitemark™ by BSI.

Selected handles in our range offer a full BS EN 1906 classification and all handles undergo two of the primary tests within the standard for durability and corrosion resistance.
