Applicable to conductive clothing, either assembled from component parts or forming a single complete clothing, worn by (electrically) skilled persons during live working (especially bare-hand working) at a nominal power system voltage up to 800 kV a.c. and ±600 kV d.c. It is applicable to conductive jackets, trousers, coveralls (one-piece clothing), gloves or mitts, hoods, shoes, overshoe socks and socks. The main changes with respect to the previous edition are listed below: - the scope has been extended to cover the use of conductive clothing to ±600 kV d.c.; - revision of the electrical resistance requirements of the fabrics used in conductive clothing; - revision of the testing procedures for complete clothing. The contents of the corrigendum of February 2003 habe been included in this copy.
