Live working - Conductive clothing

Scope

IEC 60895:2020 is applicable to conductive clothing, worn during live working (especially bare-hand working) on AC and DC electrical installations, to provide electrical continuity between all parts of the clothing and a reduction of electric field inside the clothing.

This document 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, hoods or helmets, shoes or boots, overshoe socks and socks) in electrical systems with nominal voltage up to 1 000 kV AC and up to ±800 kV DC.

This document does not indicate values of protection from the effects of the electric arc, because any value indicated would not guarantee the necessary protection from the effects of electric arcs, or the operator would need to wear very heavy and rigid conductive clothing, which would not allow the execution of the work in safety.

The products designed and manufactured according to this document 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.

This third edition cancels and replaces the second edition, published in 2002. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) increase of the use up to 1 000 kV AC and ±800 kV DC;

b) introduction of two classes of conductive clothing with different electrical requirements;

c) revision of the electrical requirements of conductive clothing;

d) definition of specific resistance values for each component part of the conductive clothing;

e) introduction of conductive helmet and conductive scarf as component parts of conductive clothing;

f) introduction of mechanical requirements and new tests for fabrics;

g) update of the cleaning test procedures;

h) revision of the efficiency test of the conductive clothing to improve the feasibility and repeatability;

i) preparation of the elements of classification of defects, and general application of IEC 61318:2007;

j) the normative Annex B for the classification of tests has been replaced by normative Annex C for the general type tests procedure, the normative Annex D for the classification of defects and the informative Annex E providing the justification for the classification of defects;

k) the normative Annex C on sampling procedure has been deleted (not applicable according to IEC 61318:2007);

l) modification of the recommended frequency of the periodic tests.
