The United Kingdom Accreditation Service (UKAS) has granted Shirley Technologies at BTTG in Manchester an extension to its schedule of accreditation to cover tests in Cleanroom, UVR Protection and Electrostatics (CUE). Many of the electrostatic tests added to the schedule are used to support certification of Personal Protective Equipment and Construction Products, which are subject to European Commission Directives. In addition to harmonised European and International standard test methods, the newly accredited tests include some that are unique to Shirley Technologies, having been developed by staff in CUE in response to advances made in materials technology.
