Locks

The following standards are suitable when specifying a replacement locking system to an existing door.

LOCKS

DHF TS 007:2014 + A2:2018 (including corrigendum No2 Enhanced Security Performance Requirements)

For replacement cylinders and/or associated security hardware

This specification includes a classification method and references test methods and acceptance criteria for the assessment of enhanced security cylinders and associated security hardware which are intended for use in the retrofit market.

It covers replaceable cylinders intended for use with rim locks, and/or mortice locks, (including euro profile, oval and threaded cylinders) and associated security hardware intended to give these cylinders protection from attack. This specification covers such cylinders and associated security hardware supplied either as a package or separately, and demonstrates enhanced security performance for replacement cylinders and/or associated security hardware.

Based upon BS EN 1303:2015 and the General Vulnerability Assessment from BS 3621, this standard incorporates additional requirements to address critical issues relating to the security provided by cylinders and associated keys.

STS 217 Issue 3: 2016

Enhanced security requirements for replacement cylinders and/or associated security hardware to meet the requirements of DHF TS007.

An equivalent test standard to DHF TS007, published by Warrington Certification.

Sold Secure SS 312  Diamond Standard

Specification for Cylinders for Locks

Based on BS EN 1303:2015 and the General Vulnerability Assessment from BS 3621, this standard incorporates additional requirements to address critical issues relating to the security provided by cylinders and associated keys.

BS 3621:2017 Lock assemblies operated by key from both the inside and outside of the door

The minimum standard for locks on external or entrance doors.

The effectiveness of the lock also depends on the quality of the door, frame and other hardware which is not tested by this standard and which may fail before the lock.

BS 8621:2017 Lock assemblies operated by key from the outside of the door and by handle or thumb turn from the inside of the door

Thief resistant locks. Keyless egress. As above but accommodating locks that offer egress without the use of a key.

BS 10621:2017 Lock assemblies in which the operating mode can be switched between the normal BS 8621 operating mode and a secure mode in which no egress is possible

Thief resistant locks. Keyless egress. As above but with external deadlock override facility. NB: Only to be used on properties with an alternative means of escape.

PAS 3621: 2011

Multipoint locking assemblies. Keyed egress.

Essentially a multipoint lock equivalent to BS 3621, utilising the same methodology i.e. key operation from both sides.

PAS 8621: 2011

Multipoint locking assemblies. Keyless egress.

Essentially a multipoint lock equivalent to BS 8621, utilising the same methodology i.e. key operation from the outside with non-key operation on the inside (thumb turn or similar).

PAS 10621: 2011

Multipoint locking assemblies. Dual mode egress.

Essentially a multipoint lock equivalent to BS 10621, utilising the same methodology i.e. key operation from the outside with non-key operation on the inside but with an additional facility to deadlock the door from the outside using a deliberate secondary positive action. NB: Such locks must only be used on properties with an alternative means of escape.

Hardware

DHF TS 002: 2009 Door viewers

Requirements and test methods for all forms of door viewer, designed to be used on doors in buildings, to allow occupants to detect and identify callers without having to reveal their own identity, or even their presence in some circumstances, to the caller.

DHF TS 003: 2012 Door chains and limiters

This standard specifies requirements and test methods for all forms of door opening restrictor designed to be used on doors in buildings.

DHF TS 008: 2015 (Including Corrigendum No.1, March 2016)

Enhanced security and general requirements for letter plate assemblies and slide through boxes

This technical specification provides a means of evaluation against an opportunist attack.  Prevention of contents being removed and potential arson attack can also be assessed.

Both letter plate assemblies and slide through letter boxes allow mail to pass directly through a door or side panel where mail is retrieved on the opposite side of the door.

DHF TS 009:2019 Letter Boxes

Enhanced security and general requirements for letter boxes where mail is retrieved from the same side as delivery

This standard covers requirements for lockable letter box assemblies that are free standing or surface mounted and where mail is retrieved from the same side as delivery.
