TS007:2012 is a Technical Specification; a document produced by the Door & Hardware Federation and the Glass and Glazing Federation.
It is a security standard for replacement lock cylinders and protective door furniture.
The standard was written in response to the growing threat of burglary, given the increased availability of information on lock attack techniques on the Internet.
TS007 uses a three star system, in which the cylinder, or a combination of the cylinder and security furniture, must have an accumulative three stars to meet the minimum security requirements.
The star rating of any given product will be indicated above the Kitemark (on the packaging), and it is up to the person fitting the furniture to ensure they have the correct combination of hardware to accumulate the three stars and comply with the standard.
