SS 312 Specification for Cylinders for Locks revison.
Lock cylinder specification SS 312 Diamond is gathering recognition and credibility now that three different manufacturers have passed testing and all manufacturers have displayed remarkable innovation during the development of their cylinders(N>B 3 have managed to test but re-submission for annual audit is required to maintain approval).
Recent significant media coverage has highlighted the problems happening in West Yorkshire and many people have been in contact with Sold Secure and the MLA looking for answers. Sold Secure is happy that it has answers already in place and approved product to offer as a solution.
Following very recent info from ACPO/Secured by Design, it has been decided to slightly change the test method in SS312. Secured by Design had already given its full backing to SS312 but gave Sold secure vital information to prove that a small change was needed. Manufacturers with the existing SS312 will retain Sold Secure accreditation until the annual audit is due and then they will be retested to the new specification. The old SS312 assumed that when someone attacked a door handle form the outside, the inside handle remained in placeand offered support to the cylinder(this was witnessedmany hundreds of times at various UKAS test houses across the UK). Secured by design highlighted that if a security/PAS24 handle was attacked it could eventually snap in a different way and the inner handle would fall off thereby offering no support to the cylinder at all. Depending on the design of cylinder this could in turn enable manipulation of the lock case to open.
This all means that because SS312 is a specification for retro fit cylinders, we would never be sure what kind of handle or security furniture the cyliner would be used with. The solution is to test with non-attack side furniture in place and then test without to cover all scenarios. The cylinders will have to pass the test with and without furniture in order to achieve the coveted Sold Secure 312 Diamond accreditation.
Secured by Design are a constant source of information and are happy to promote SS312(latest revision to be published on December 1st 2011) as well as Ts 007(recently published) as they both achieve the same result. West Yorkshire police in particular will be promoting SS312 heavily as a solution to cylinder attacks with prevalance of snappingin their area, and we expect other police forces will follow suit as crime figures begin to fall.
Ts 007 is expected to use a very similar test method for a 3 star rated, however TS 007 will also allow a lesser one star rated cylinder as long as it is used with a 2 star rated handle. Ts 007 has been written by DHf (Door and Hardware Federation) and GGf(Glass and Glazing Federation) with input from Secured by Design but Sold Secure and the MLA believe that the combination or star rated solution could get very confusing and possibly let the public think that they have upgraded security when in fact they have not, for example a 1 star rated cylinder in a non-security(I.e standard) handle is still vunerable to attack. Also, would the public not think that having a 2 star handle without a kitemarked cylinder is better security than a 1 star kitemarked cylinder? Both 1 and 3 star cylinders could display a Kitemark, so the possibility to confuse the public is obvious.
