PAS 23 and PAS 24

3 min read Doors

What are PAS 23 and PAS 24?

Doors should be safe and durable, as well as able to stand the test of time (and busy homes!). Door testing standards ensure consumers that when they purchase a new door, it will be safe, secure and fit for purpose.

All doors manufactured in the UK must comply with British manufacturing and performance standards. PAS 23 and PAS 24 are two of these standards.

PAS 23

PAS 23 assesses the ability of door assemblies to match performance requirements. A door is subjected to a series of tests, which include wind and water tightness and cycle testing. Every component used within the door set must be tested and meet the relevant British Standard for that component. The door can then be put forward for testing to PAS 23.

It's important to note that PAS 23 is no longer used and has since been replaced with BS6375.


Like PAS 23, BS6375 covers wind and water tightness tests, and every component used in the door set be tested to the relevant British Standards. However, it also covers strength and operation characteristics, and other additional performance characteristics.

PAS 24

PAS 24 is an enhanced security performance test for door assembly requirements. As with PAS 23 testing, each door component must comply with the relevant British Standard for that component. PAS 24 covers the same requirements as PAS 23, with the addition of a number of security tests such as manual intervention and mechanical loading. PAS 24 testing is intense and rigorous. The mechanical loading tests subject doors to 4.5Kn of pressure (approximately 45 times the pressure used to tighten a car wheel nut!)

What are the PAS 24 requirements?

PAS24 is a minimum standard, meaning the doors that are tested to the specifications of PAS 24 will either pass or fail. There are no higher or lower grades available, but this does not mean that every door will be equally secure - some doors that pass will be stronger than the minimum requirements.

This also applies to any door side panels or any windows that adjacent to door sets.

BS EN356:2000

This British Standard specifies the requirements and test methods for security glazing. These tests cover the glazing's ability to delay access to objects and/or persons to protected spaces for a short period of time. Any security glazing must protect spaces for a minimum amount of time in order to pass this standard.

“Used the Sheerwater team to replace a couple of Velux windows in our converted loft. Really first class experience, great communication throughout, super professional and the installation was the best we've had in terms of fit and finish and (lack of) damage to surrounding areas. Will use again!”Tim Loake
