There are two alternative standards certifying the level of security protection offered by a doorset:
In short PAS24 is less secure than either LPS1175 or ENV 1627, and offers a basic level of enhanced security for residential applications.
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.
The levels of resistance offered by security products certified to the PAS 24 standard are generally lower than that provided for within LPS 1175. The permitted attack time specified under PAS 24 does not exceed 6 minutes under any of the required tests, in comparison to a maximum of 20 minutes under LPS 1175. This would suggest that products certified to the PAS 24 standard would be best used in those locations where a burglar is keen to avoid excessive noise and potential detection; such as in built-up areas or on busy thoroughfares.
BS EN 1627 is the the European Standard for the burglar resistant classifications of domestic and commercial doorsets, windows, curtain walling, grilles and shutters. BS EN 1627 is also the published British Standard by the British Standards Institute. The standard was developed by the CEN — the European Committee for Standardisation, comprised of the national standardisation bodies of 34 European countries. EN 1627 forms part of a series of European security standards (EN 1627 – EN 1630) with the aim to implement an industry-standard, minimum level of enhanced security for doorsets and windows across the EU.
EN 1627 was developed with the intention of creating a standard that was as good as, or better than, each respective countries existing standards.
There are 6 resistance classifications (RC) which comprise the EN 1627 standard, and determine the level of burglar resistance offered by a security product. Classes RC1 – RC3 are primarily focused on the levels of attack associated with the casual or opportunistic intruder. Classes RC4 – RC6 are associated with the more experienced or professional intruder and cover targeted attacks. 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 LPS1175 and ENV1627 are considered to be on par, with PAS 24 offering a lower level of security.
