标准范围

IEC 60895:2020适用于在交流和DC电气装置上带电工作（尤其是徒手工作）期间穿着的导电服装，以提供服装所有部分之间的电气连续性并减少服装内部的电场。本文件适用于由导电服装（形成一体式服装的夹克和裤子或工作服）和导电部件（手套、头罩或头盔、鞋子或靴子、套鞋和袜子）组装而成的导电服装，标称电压高达1 000 kV AC和±800 kV DC的电气系统。本文件没有指出防止电弧影响的值，因为任何指示的值都不能保证防止电弧影响的必要保护，或者操作员需要穿非常重和坚硬的导电衣服，这将不允许安全地执行工作。根据本文件设计和制造的产品有助于用户的安全，前提是这些产品由经过工作培训的人员按照带电工作方法和使用说明使用。第三版取消并取代了2002年出版的第二版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:a)将使用增加到1 000 kV AC和±800 kV DC；b)引入两类具有不同电气要求的导电服装；c)修订导电服装的电气要求；d)导电服装的每个组成部件的特定电阻值的定义；e)引入导电头盔和导电围巾作为导电服装的组成部分；f)介绍织物的机械要求和新测试；g)清洁测试程序的更新；h)修订导电服装的效率测试，以提高可行性和可重复性；i)缺陷分类要素的准备，以及IEC 61318:2007的一般应用；j)用于试验分类的规范性附件B已被用于一般型式试验程序的规范性附件C、用于缺陷分类的规范性附件D和提供缺陷分类理由的资料性附件E所取代；k)关于取样程序的规范性附录C已被删除（根据IEC 61318:2007不适用）；l)修改定期测试的推荐频率。

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.
