Door Standards

The standards listed below are for complete doorsets.  A doorset is a complete door assembly consisting of the door frame, door leaf (or leaves), hardware and any integral side panel or fanlight.


PAS 24: 2016

Enhanced security performance requirements for doorsets and windows in the UK. Doorsets and windows intended to offer a level of security suitable for dwellings and other buildings exposed to comparable risk

This PAS supersedes PAS 24: 2012 (withdrawn) with effect from 28th February 2016 and provides a method for testing and assessing the enhanced security performance requirements of doorsets and windows.  It covers doorsets and windows of all material types. Products must also meet the general performance requirements as listed below:

BS 6375-1:2015+A1:2016Performance of windows and doors - Part 1: Classification for weather tightness and guidance on selection and specification

BS 6375-2:2009 Performance of windows and doors – Part 2: Classification for operation and strength characteristics and guidance on selection and specification

BS 6375-3:2009+A1:2013 Performance of windows and doors Part 3: Classification for additional performance characteristics and guidance on selection and specification

BS 6375 parts 1, 2 & 3 certifies that a particular doorset is fit for purpose. These standards have replaced PAS 23:1999 which has been withdrawn.

The test is designed to mimic an attack by an opportunistic burglar, using tools which are easy to conceal.

STS 201 Issue 12: 2020

Enhanced security to satisfy the requirements for certification of doorsets, tested in accordance with PAS24 & BS6375

As the title suggests, this is an equivalent test standard to PAS 24.  It incorporates fitness for purpose testing, and is published by Warringtonfire Testing and Certification Limited.

STS 202 Issue 8: 2019

Requirements for burglary resistance of construction products including hinged, pivoted, folding or sliding doorsets, windows, curtain walling, security grilles, garage doors and shutters

This is an enhanced test specifying a similar range of attack tools and times to those at the lower levels of LPS1175, including attacks with power tools. However, STS202 does not extend to cover the higher levels of risk addressed within LPS1175 and the attack methods used differ.  It is published by Warringtonfire Testing and Certification Limited.

LPS 1175: Issue 8.0

Requirements and testing procedures for the LPCB certification and listing of intruder resistant building components, strongpoints, security enclosures and free-standing barriers

Documentation states:

This standard is concerned with physical security, including products manufactured for perimeter, façade, internal spaces and entrapment protection. The higher the security rating, the more formidable the security product.

One of the more substantial revisions to the standard to date, LPS 1175: Issue 8 has been devised to improve the testing guidelines for security products, enabling a far more realistic scope for security ratings. There are a possibility of 48 Security Ratings aimed at creating strategic delay via physical security.

LPCB describe it as:

“Developed following extensive consultation with stakeholders, this revision sees the previous single digit performance classifications (i.e. security ratings 1 to 8) extended to one formed of two elements that illustrate performance in terms of:

Threat level (first element) – Letter (A to H) corresponding with the tool kit used to evaluate the product’s intruder resistance and number of attackers involved.

Delay (second element) – Numeric value (1, 3, 5, 10, 15 or 20) corresponding with the minimum delay (in minutes) provided by the product when placed in a locked condition.”

This revision provides property developers, architects and other security professionals the opportunity to layer their security beyond the capability of previous revisions.

LPS 1175 Issue 8 is the latest revision acceptable to SBD however, some of the older issues are still relevant for historical reasons.  For further information please contact SBD or your local DOCO.

LPS 2081: Issue 1.1

Requirements and testing procedures for the LPCB approval and listing of building components, strongpoints, security enclosures and free-standing barriers offering resistance to intruders attempting to use stealth to gain entry

LPS 2081 specifies two grades of security according to the tools and time taken by an intruder in situations where they want to avoid making excessive noise, replicating a stealth attack common in a residential environment. When LPS 2081 is used as a route to gain SBD approval, SRB is the minimum requirement for a doorset.
