This International Standard is applicable to conductive clothing, worn during live working (especially bare-hand working) on a.c. and d.c. electrical installations, to provide electrical continuity between all parts of the clothing and a reduction of electric field inside the clothing. The standard is applicable to conductive clothing assembled from a conductive garment (jackets and trousers or coveralls forming a one-piece garment) and from conductive component parts (gloves or mitts, hoods or helmets, shoes or boots, overshoe socks and socks) in electrical systems with nominal voltage up to 1000 kV a.c. and up to ± 800 kV d.c. The products designed and manufactured according to this standard contribute to the safety of the users provided they are used by persons trained for the work, in accordance with the live working methods and the instructions for use.
