There are two alternative standards certifying the level of security protection offered by a doorset:
This standard is primarily aimed at residential applications, where an intruder is likely to use stealth to avoid attracting attention. The PAS (Publicly Available Specification) 24 test standard was introduced by the British Standard Institute (BSI) in collaboration with industry stakeholders and Secured By Design (SBD), an official UK police initiative. It was created in an effort to implement an industry-standard, minimum level of enhanced security for domestic doorsets and windows in the UK.
It is of note that EN 1627 does not match the scope of PAS 24 in addressing all known burglary methods, including lock picking attacks. SBD clearly advise that certification of products via the PAS 24 standard is the preferred route to compliance, owing to failure of EN 1627 to address key areas of security, exposing possible product vulnerabilities. If a manufacturer certified under EN 1627 did want to match the security standard of PAS 24, their product would need to achieve successful testing to EN 1627 class RC3. In addition, the product would need to satisfy additional testing of the cylinder and letterplate as detailed in PAS 24.
This standard represents a world-class certification of physical security protection (e.g. doors and windows) for buildings and facilities, as set by the LPCB (Loss Prevention Certification Board). The LPCB have worked with industry, insurers, risk assessors and government for over 100 years to set standards that ensure security products and services perform as claimed, and effectively work to ensure buildings are kept safe and secure.
There are 8 levels of security ratings (SR) which comprise the LPS 1175 standard. SR 1 and 2 are ideally suited to protect against risks to residential properties; SR 2, 3 and 4 cover threats to commercial buildings; SR 4 and 5 represent high security risks; whilst SR 6, 7 and 8 incorporate protection for extremely high security facilities. Although the maximum attack times under RC2, RC3 and RC4 of EN 1627 correspond to SR2, SR3 and SR4 of LPS 1175 (i.e. 3 minutes, 5 minutes and 10 minutes respectively), it is of note that LPS 1175 utilises a broader range of tools and attack methods (including those which involve noise) to establish its classifications.
Direct comparisons between the three standards can be a challenge owing to the differences in methodologies and pass levels; in general UK manufacturers work to the LPS 1175 and PAS 24 standards, whilst European suppliers commonly adhere to EN 1627.
