The Door & Hardware Federation has launched the revised technical specification, DHF TS 008:2022, Enhanced Security and General Requirements for Letter Plate Assemblies and Slide Through Boxes.
This supersedes DHF TS 008:2015, which is now withdrawn.
The document provides a means of evaluation against opportunist attack and defines the classification required for testing for a compliant product, in particular, letter plate assemblies that enable mail to pass directly through a door or door side panel. It applies to complete letter plate assemblies and slide through boxes placed on the market, either fully assembled or as a kit.
DHF general manager and secretary Michael Skelding explained: “The new TS 008 document has been updated by the building hardware technical committee and now supersedes the original specification from 2015. In the new standard, the ‘fishing’ test has been improved to ensure that compliant products have adequate resistance to key fishing.
“To meet the constantly varying challenges of burglary and theft it is important to update security standards such as TS 008. In carrying out this project, DHF has been supported by its manufacturing members as well as by test laboratories and the Police Secured by Design scheme. Manufacturers will be upgrading their products to meet the new standard; we hope that, by setting this new benchmark for performance, we will ultimately be helping to reduce opportunities for burglary and theft throughout the UK.
