What is BS 10621:2017+A1:2024 - Lock assemblies about?
An amended standard that reflects the changing modus operandi of thieves, BS 10621:2017+A1:2024 gives performance requirements and test methods for a thief-resistant mechanically operated single-point lock assembly.
Who is BS 10621:2017+A1:2024 - Lock assemblies for?
Users of this standard will include:
- manufacturers, fabricators and suppliers of secure doorsets and windows;
- building specifiers;
- architects;
- standards bodies;
- certification bodies;
- test houses and laboratories; and
- trade associations.
What does BS 10621:2017+A1:2024 - Lock assemblies cover?
BS 10621:2017+A1:2024 specifies performance requirements and test methods for a thief resistant mechanically operated single-point lock assembly (including locking plates, fixing screws, fitting instructions, cylinders and protective furniture where appropriate) that:
a) incorporates a lock conforming to BS EN 12209:2016 that can be locked from both sides with a key thereby only allowing key egress; and
b) is used in doors, window doors and entrance doors in buildings.
BS 10621:2017+A1:2024 does not cover thief-resistant lock assemblies that provide keyless egress, i.e. lock assemblies that can always be unlocked from the inside without the need for a key, or lock assemblies that provide a secure (no egress) mode in addition to keyless egress.
NOTE 1: Thief-resistant lock assemblies that provide keyless egress or assemblies that provide a secure (no egress) mode in addition to keyless egress are specified in BS 8621 and BS 10621 (respectively), because they are sufficiently different in terms of what they offer for means of escape (from fire) and security.
NOTE 2: It is possible that lock assemblies conforming to this standard might not be suitable for use on doors constructed from certain types of material, e.g. plastic or aluminium.
Why should you use BS 10621:2017+A1:2024 - Lock assemblies?
- Enhanced security: Manufacturers will use BS 10621:2017+A1:2024 to demonstrate that their lock assemblies meet the requirements to be considered as providing enhanced security.
- Building regulations: The security requirements of BS 3621, BS 8621 and BS 10621 are referenced in Approved Document Q Annex B (English and Welsh versions), as a method of demonstrating that locksets contribute to security.
- Police approval: Certification to BS 10621 is one way for lock assemblies to meet the requirements of the UK Police Service ‘Secured By Design Scheme’.
- Thief resistance: BS 10621:2017+A1:2024 reflects the changing modus operandi of UK thieves.
- Market differentiation and competitiveness: Manufacturers can differentiate their products in the marketplace by gaining certification to BS 10621:2017+A1:2024. This demonstrates that products meet enhanced security requirements, increasing their appeal to specifiers and end-users.
- Reliability: It helps ensure lock assemblies are manufactured consistently and efficiently.
What has changed?
BS 10621:2017+A1:2024 supersedes BS 10621:2017, with this amendment adding clarification to the test methods and updating references to industry documents.
