Introduction
This document complies with the electrical insulating requirements set out by CLC/TC 78 and with the
non-electrical requirements set out by CEN/TC 162. This insulating clothing is recognized as a PPE
according to PPE Regulation 2016-425.
Electrical insulating protective clothing was developed primarily for use by workers for work on low-
voltage overhead lines.
For the moment, there is no withstand test applicable to products where the principle risk is of
unintentional contact with live parts, and such a test is not included in the present document. However,
despite this Iack, it is considered that a satisfactory Ievel of electrical protection is provided by
compliance with this document for both the proof tests and the periodic electrical inspections.
For the moment, no test is available in relation to the risk of workers exposure to an electrical arc
generated by Iow-voltage installations. This task is presently under study by CLC/TC 78 WG 7.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
Terms defined in Clause 3 are given in italic print throughout this document.

1 Scope
This document is applicable to electrical insulating protective clothing used by skilled persons when they
are working on or near live parts of Iow-voltage installations at nominal voltages up to 500 V AC or 750 V
DC.
The purpose of this clothing when used in conjunction with othe
