Standards - BS EN 10621:2017+A1:2024
The BS EN 10621:2017+A1:2024 standard pertains to specialized lock assemblies that offer switchable modes between regular operation and a secure mode where egress (or exit) is restricted. This standard, maintained by the British Standards Institution (BSI) under the B/538/4 committee, addresses locks that comply with BS 8621 operational standards in one mode while allowing for heightened security in another, making them suitable for scenarios requiring controlled access and restricted exit capabilities.
Released as an amendment in 2024, BS EN 10621:2017+A1:2024 responds to evolving security needs within buildings, particularly in commercial or residential settings where flexibility in locking mechanisms enhances both safety and security. One of the key aspects of this standard is its requirement for lock mechanisms to shift between two distinct functionalities. The "normal" mode operates under BS 8621 standards, focusing on locks that allow egress without a key (useful for emergency exits), while the secure mode restricts exit, which is often needed in environments where security trumps immediate egress, like high-security zones within buildings.
The technical specifications and implementation guidelines of BS EN 10621:2017+A1:2024 are detailed across 18 pages and classify these locks under the International Classification for Standards (ICS) category 91.190, related to building accessories. Compliance with this standard means that building and security managers can implement locks that align with regulatory requirements and ensure a balance between security needs and safety protocols. The standard is particularly relevant for architects, builders, and security consultants who must adhere to national standards while designing facilities that include restricted access zones
