PAS 24 is an enhanced security performance test for door assembly requirements,  every component used within the door set tested must comply to the relevant British Standard for that component.

PAS 24 includes several security tests, such as:

• Manual intervention
• Mechanical loading
• Hard and soft body impact

An example of the intensity of the testing, the mechanical loading tests subjects the door set to 4.5Kn of pressure, the equivalent of approximately 45 times the pressure used to tighten a car wheel nut.

TS 007 is a security standard relating to the door handle and cylinder combination used on a door. To achieve TS 007 status, the combination used must total 3 stars.

A cylinder can achieve either 1 or 3 star classification, where as a door handle can only ever achieve 2 stars.

Therefore, it is possible to achieve 3 star accreditation by combining a 1 star cylinder with a 2 star door handle. Or, just using a 3 star cylinder alongside an unaccredited door handle. See our simple diagram below.

Achieving TS007 is vital in order to pass any door to PAS 24 or achieve Secured by Design.

Anti-Snap – the cylinder has a section or sections, often called a sacrificial cut, either side of the central lock mechanism that will come away if the cylinder was to be attacked from the outside, however leaving the remainder of the cylinder mechanism intact and locked.

Anti-Pick – the top half of the pin stack inside the cylinder are designed to include a mushroom shape or indent. Therefore, if something was used to pick the cylinder it would catch on the pins and prevent the cylinder from unlocking.

Anti-Bump – cylinders are designed to have more pins (generally 6) and a shallow pin stack. By doing this it means that if a bump key was knocked into the cylinder, the pins would not jump up meaning the cylinder could not be bumped.

Anti-Plug/Core Extraction – the cylinder has strengthened steel circlips that hold the cylinder in place so the core cannot be extracted from the cylinder.

Anti-Drill – the cylinder has plates and pins built in and this prevents the cylinder core being turned if the pin stack was attacked by a drill. It is designed to break the drill bit and protect the integrity of the cylinder to prevent entry.

BS EN 1303 is a British Standard relating to cylinders. It is broken down into 8 digits and ensures that the cylinders are tested to the highest standard. The 8 digits are; Category of Use, Durability, Test Door Mass, Fire Resistance, Safety, Corrosion and Temperature Resistance, Key Related Security and Attack Resistance.

Cylinders are graded based on this criteria.
