The Standard UL 60950-1, which defines the requirements pertaining to the electrical safety of IT equipment, is used as the basis for testing IT equipment. This also includes requirements placed on materials with regard to thermal stability, insulating property and flammability.
EK1-ITB 2000
GS (Tested Safety) is a German test mark that can be issued by various inspection agencies such as, e.g. VDE, TÜV Rheinland or UL. The basis for issuance of the test mark is the award principles governed by EK1 ITB-2000. These award principles are revised and augmented, where necessary, on an annual basis by various inspection agencies. The standards referenced therein include ones for product safety such as, e.g. EN 60950-1 or for ergonomics such as, e.g. DIN EN ISO 9241-4xx. The GS test principles are available on the Internet site for ZLS http://www.zls-muenchen.de/ in the shared resources category "Erfahrungsaustausch"/EK1.
