Enclosed low-voltage switchgear and controlgear assemblies. Guide for testing under conditions of arcing due to internal fault1 Scope This technical report gives guidance on the method of testing of assemblies under conditions of arcing in air due to an internal fault. The purpose of this test is to assess the ability of the assembly to limit the risk of personal injury, damage of assemblies and its suitability for further service as a result of an internal arcing fault. The test procedure given in this technical report applies only: to enclosed, floor standing or wall

specifies a method for the determination of the compressive strength of test specimens of hardened concrete
