This International Standard further gives guidelines and recommendations on the measures to achieve EMC in the electrical and electronic installations of the following equipment groups:

and intended to be used in industrial locations

4 Background

BS EN 3475-803 specifies a method for measuring the capacitance variation in a cable (multipair cables)

trimmers and other similar causes are excluded

It is suitable for use as cable protection in areas where wiring is subject to contamination by aircraft fuels and hydraulic fluids

with the exception of liquefied gases

E1 to E4 and F1 to F3 in IEC 60404-1

and the relevant standard specifying the gauge blanks

Embedded substrate technology is the inclusion of at least one active or passive electrical component within the conductive layers of a substrate

The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different concrete structures
