Sold Secure DiamondSold Secure Diamond – a standard you can trust

Sold Secure is the premier testing and certification house for security products. Sold Secure is owned by the Master Locksmiths Association, the largest and longest established trade association for the locksmithing industry, (effectively the experts in locks).

It is the Mission of Sold Secure to test and provide professional and accurate advice regarding effective security products to commercial customers, the insurance industry, the Home Office, the Police and the public.

Sold Secure is a company dedicated to reducing the risk of theft by the assessment of security products. Sold Secure was established in 1992 by Northumbria and Essex Police with the help and backing of the Home Office.

The scheme has close ties with a number of constabularies and insurers who provide regular information regarding the methods of theft and the tools utilised by criminals in their area. This helps to maintain an up to date specification and means security products can be assessed in the light of the risk they are likely to encounter when in use.

Sold Secure Diamond for CylindersSold Secure‘s only source of income is from the fees it levies to undertake its work. However, as the company does not have to pay dividends to shareholders it is able to offer its services at very competitive rates. All surplus income is reinvested in crime prevention.

Sold Secure has launched a revised version of its SS312 specification relating to the testing of lock cylinders. This includes the new Diamond Level which introduces a new test specifically aimed at replicating the snapping attack that is becoming more popular amongst thieves.

This Diamond level test incorporates all the cylinder vulnerability testing of BS3621 and EN1303 and extra tests specifically aimed at the snapping of cylinder in numerous different ways.

Sold Secure Diamond is the harshest test a Euro Profile cylinder can take.

The test rig for the Diamond Level testing is shown on the left.

As you can see, the cylinder is afforded no protection, and is attacked directly, with a number of different tools to replicate snapping, pulling and forcing experienced in real life attacks.

The large hole around the cylinder replicates poor routing and / or flexible material that the product may be fitted into.

The Diamond test therefore replicates worst case scenario for fitting, and assumes correctly that handles offer no resistance against snapping.

Therefore the Sold Secure Diamond test is the only standard that should be recommended for replacement locks, as it is the only test that effectively tests for snapping and takes into account all possible materials.
