The Sold Secure Diamond Standard

Sold SecureSold Secure, the security product test house owned by the Master Locksmiths Association started work over 6 years ago on a test standard to replicate known methods of attack on euro cylinders.

SS312 Diamond was introduced which is considered to be the highest level of approval for lock cylinders, and includes robust tests to determine a euro cylinder locks resistance against snapping.


BSI TS007:2014 is a test specification for euro cylinders and security hardware. TS007 is aimed at protecting cylinder locks against all known methods of forced entry, including picking, manipulation, bumping and snapping, and sets out to provide a way to upgrading the cylinder security of your door.

Cylinder and hardware solutions that have successfully met the requirements of the standard will be marked in accordance with a star rating scheme, with a cumulative total of three stars being necessary to provide complete security.

This can be in the form of a 3 star rated cylinder capable of resisting all attack, or a combination of a one star anti manipulation cylinder with two star protective hardware such as a security handle or cylinder guard.
