BS EN 62153-4-2 describes the injection clamp test method which determines the screening attenuation (as) of coaxial cables and the coupling attenuation (ac) of balanced shielded or unshielded data cables in a frequency range from 30 MHz up to 1

including complex service supply chains

The calculation of bending moments due to traffic loads under normal service conditions is based on the elastic behaviour of the track

by using BS EN 61158-6-11 together with other standards positioned within the OSI or fieldbus reference models
