WG 13 - TC 78/WG 13

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;

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;

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.

IEC 60984:2014 is applicable to electrical insulating sleeves for the protection of workers from accidental contact with live electrical conductors, apparatus or circuits. The products designed and manufactured according to this standard contribute to the safety of the users provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use. Unless otherwise stated, in this standard the term "sleeve" is used for "electrical insulating sleeve". This second edition cancels and replaces the first edition, published in 1990 and its Amendment 1 published in 2002. It constitutes a technical revision which includes the following major changes:
- removal of the requirement for an area to mark the date of inspection;
- only the straight mounting method with water electrodes is specified for the dielectric type test;
- the d.c. electric tests are no longer included in the normative part of the document, but a new informative Annex E is added;
- preparation of the elements of evaluation of defects, and general application of IEC 61318:2007;
- in the new normative Annex F, updating of the characteristics of the liquid specified for tests on sleeves of category H, according to the latest edition of ISO 1817;
- introduction of a new normative Annex G on classification of defects;
- introduction of a new informative Annex H on the rationale for the classification of defects;
- and for periodic electrical retesting, recommended voltage limit of the dielectric test methods to 10 kV except in case of the test method with water electrodes and straight mounting.

IEC 61482-1-1:2009 specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame-resistant clothing for workers exposed to the thermal effects of electric arcs and the function of garments using these materials. These test methods measure the arc thermal performance value of materials which meet the following requirements: less than 100 mm char length and less than 2 s afterflame after removal from flame, when tested in accordance with ISO 15025, procedure B (bottom-edge ignition) on the outer material, and the char length measured using a modified ISO method as described in Annex A. These methods are used to measure and describe the properties of materials, products, assemblies or garments, in response to convective and radiant energy generated by an electric arc in open air under controlled laboratory conditions. The materials used in these methods are in the form of flat specimens for method A and garments for method B. Method A is used to determine the arc rating of materials and material assemblies when tested in a flat configuration. Method B is used to measure garment response, not arc rating, to an arc exposure including all the garment findings, sewing thread, fastenings, fabrics and other accessories when tested on a male mannequin torso. Method B is also used for accident replication.

IEC 61482-2:2009 is applicable to protective clothing used in work if there is an electric arc hazard. Specifies requirements and test methods applicable to materials and garments for protective clothing for electrical workers against the thermal hazards of an electric arc based on:
- relevant general properties of the textiles, tested with selected textile test methods, and
- arc thermal resistance properties, such as:
a) the arc rating of materials (ATPV or EBT50), when tested with an open electric arc under defined laboratory conditions according to IEC 61482-1-1, or
b) the arc protection class of materials and garments (Class 1 or Class 2), when tested with a directed and constrained electric arc under defined laboratory conditions according to IEC 61482-1-2.
Requirements of this standard do not address electric shock hazards. The present standard is applicable in combination with standards covering such hazards.

IEC 61230:2008 is applicable to portable equipment, with or without matching connection points, for temporary earthing or earthing and short-circuiting of electrically isolated or de-energized a.c. and d.c. installations, distribution and transmission networks, whether they are overhead or underground or of low or high voltage. This standard covers equipment comprising an earthing or a short-circuiting or an earthing and short-circuiting device and insulating component. The performance of equipment, devices and components covered by this standard is based on electro-dynamic and electro-thermal effects acting during short-circuit. The withstand capability of the devices and equipment is expressed by their rated values of current, time and peak factor. No rated voltage is given, but the geometrical dimensions of the equipment are also linked to the voltage of the installation. This second edition cancels and replaces the first edition published in 1993. It constitutes a technical revision. The major changes are:
- extension of the scope to cover the use of equipment on d.c. installations;
- extension of the use of aluminium to all conductive parts of the device;
