Introduction
CENELEC/TC 78 is of the opinion that clothing fullfilling this Technical Specification, ensures that
the consequences for workers, after exposure to electric arcs, will not be aggravated by the
clothing itself.
This Technical Specification specifies tests and classification for materials and clothing for
wearing when at risk of exposure to an electric arc.
The addition of a box to the test rig increases the electric arc energy affecting the test material.
This is an attempt to create a realistic scenario.
Specific dangers from accidental electric arcs arise from the high temperature, the pressure surge
and the evaporation and spatter of hot and molten metal, the effects of heat flux, noise,
UV-emissions, hot oil or the consequences of physical and mental shock.
This Technical Specification does not include electrical insulation protection.
1 Scope
The purpose of this Technical Specification is to ensure that the consequences for workers of
exposure to electric arcs, will not be aggravated by the clothing itself.
The Technical Specification does not include protection from current passing through the human
body nor thermal protection from the heat/energy generated by the electric arc.
The clothing shall be made of materials that have passed the Method 1 test.
The test methods are divided into two parts :
− method 1: Testing of material;
− method 2: Testing of clothing.
2 Normative references
The following referenced documents are indispensable for the application of this document. For
dated references, only the edition cited applies. For undated references, the latest edition of the
referenced document (including any amendments) applies.
ISO 3175-2 1998 Textiles - Dry cleaning and finishing - Part 2: Procedures for
tetrachloroethene
ISO 6330 1984 Textiles - Domestic washing and drying procedures for textile testing
3 Definitions
For the purposes of this Technical Specification, the following definitions apply.
3.1
electric arc
self-maintained gas conduction for which most of the charge carriers are electrons supplied by
primary-electron emission (IEV 121-03-12). The electric arc is generated by gas ionisation arising
from an unintentional electrical conducting connection between line conductors or between a line
conductor and the earth path of an electrical installation or an electrical device
3.2
arc tested clothing
clothing which does not aggravate the electric arc consequences, by catching fire or by melting
onto the skin
3.3
material
the material(s) of which the garment is made, this may consist of single or multiple layers
3.4
garment
a single item of clothing
3.5
clothing
an assembly of garments worn by workers
3.6
burnin
