In essence this is your guarantee that the production of the door you are purchasing is being monitored by a UKAS accredited certification body to ensure compliance with PAS 24:2016 Enhanced security performance requirements for doorsets and windows in the UK. External doorsets and windows intended to offer a level of security suitable for dwellings and other buildings exposed to comparable risk and the specific and the relevant material specific standard for general performance referenced in BS 6375 Parts 1, 2 and 3.
PAS 24, like most British Standards, is a minimum standard. In other words it doesn’t include higher or lower grades for security and so doors that are tested to the specifications of the standard either pass or fail. Although some of the doorsets that pass will be a little stronger than the minimum required, a minimum standard encourages engineers to design the door to pass at the minimum requirements. This makes economic and environmental sense and the effectiveness of doors certificated to this standard has proven that the minimum levels set by the British Standards were just about spot on.
The process of testing and certification
The manufacturer of the door submits a range of doors to a United Kingdom Accreditation Service (UKAS) accredited test house for testing to PAS 24 and the relevant ‘fit for purpose’ standards. Having achieved passes on these doors the factory and the manufacturing processes are examined by a UKAS accredited Certification Body. Providing the independent certification body is satisfied with the manufacturing facility and the way in which it is managed they will award a certificate to the manufacturer, which will enable them to market their doors as ‘certificated’ to PAS 24 and the ‘fit for purpose’ standards.
Fit for purpose’ standards for doors
BS 6375-1: 2009 Performance of windows and doors. Classification for weathertightness and guidance on selection and specification
BS 6375-2: 2009 Performance of windows and doors. Classification for operation and strength characteristics and guidance on selection and specification
BS 6375-3: 2009 Performance of windows and doors. Classification for additional performance characteristics and guidance on selection and specification
PAS 23-1: 1999 General performance requirements for door assemblies. Single leaf, external door assemblies to dwellings
BS 6510: 2005 Steel-framed windows and glazed doors
BS 7412: 2007 Specification for windows and doorsets made from unplasticized polyvinyl chloride (PVC-U) extruded hollow profiles
BS EN 12608:2003 Unplasticized polyvinylchloride (PVC-U) profiles for the fabrication of windows and doors. Classification, requirements and test methods
To ensure that the quality of manufacture is maintained, the Certification Body will regularly visit the production facility and periodically re-test the products to make sure that they are still performing to the standards. If the manufacturer changes a component part of the door they are obliged to inform the Certification Body who might require a re-test. During the initial and periodic retests the tester can attempt various procedures for up to 3 minutes each. Because these tests are conducted under strict laboratory conditions, where the tester has an opportunity to inspect the door beforehand, then it is reasonable to assume that the door’s performance is likely to better out in the field. Some of these PAS 24 doors have proved so effective that the police service has had to reconsider its methods of forcing an entry when executing a warrant to arrest drug dealers and the like!
