Méthodes d'essai d'arc électrique pour Störlichtbogenprüfverfahren für

This European prestandard was approved by CENELEC on 2000-09-15 as a prospective standard for
provisional application. The period of validity of this ENV is limited initially to three years. After two years the
members of CENELEC will be requested to submit their comments, particularly on the question whether the
ENV can be converted into a European Standard (EN).
CENELEC members are required to announce the existence of this ENV in the same way as for an EN and
to make the ENV available promptly at national level in an appropriate form. It is permissible to keep
conflicting national standards in force (in parallel to the ENV) until the final decision about the possible
conversion of the ENV into an EN is reached.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This European Prestandard was prepared by the Technical Committee CENELEC TC 78, Equipment
and tools for live working.
The text of the draft was submitted to the questionnaire and vote procedure and was approved by
CENELEC as ENV 50354 on 2000-09-15.
The following date was fixed:
- latest date by which the existence of the ENV
has to be announced at national level (doa) 2001-07-01

Introduction
CENELEC/TC78 is of the opinion that clothing fullfilling this Prestandard, ensures that the
consequences for workers, after exposure to electric arcs, will not be aggravated by the clothing
itself.
This Prestandard 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 Prestandard does not include electrical insulation protection.
1 Scope
The purpose of this Prestandard is to ensure that the consequences for workers of exposure to
electric arcs, will not be aggravated by the clothing itself.
The Prestandard 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
This European Prestandard incorporates by dated or undated reference, provisions from other
publications. These normative references are cited at the appropriate places in the text and the
publications listed hereafter. For dated references, subsequent amendments to or revision of any
of these publications apply to the European Prestandard only when incorporated in it by
amendment or revision. For undated references the latest edition of the publication referred to
applies.
