BS EN 50525-1:2011+A1:2022 PDF

Scope: This European Standard gives the general requirements for rigid and flexible energy cables of rated voltages U0/U up to and including 450/750 V AC, used in power installations and with domestic and industrial appliances and equipment. current systems is permitted. requirements. For example for buildings with high levels of public access, additional fire performance requirements may be applicable, The test methods for checking conformity with the requirements are given in other standards (see Introduction). The particular types of cables are specified in EN 50525-2 (series) and EN 50525-3 (series). The individual parts within those two series are collectively referred to hereafter as "the particular specifications". Only the sizes (conductor class, cross-sectional area), number of cores, other constructional features and rated voltages given in the particular specification apply to the individual cable type. The code designations of these types of cables are in accordance with HD 361.
