IEC 61482-2:2009

Live working - Protective clothing against the thermal hazards of an electric arc - Part 2: Requirements

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.

Travaux sous tension - Vêtements de protection contre les dangers thermiques d'un arc électrique - Partie 2: Exigences

La CEI 61482-2:2009 est applicable aux vêtements de protection utilisés pour réaliser des travaux lorsqu'il y a un danger d'arc électrique.Spécifie les exigences et les méthodes d'essai applicables aux matériaux et aux articles d'habillement utilisés pour les vêtements de protection des travailleurs électriques contre les dangers thermiques d'un arc électrique, lesquelles se basent sur
- les propriétés générales des textiles qui s'appliquent, vérifiées à l'aide de méthodes d'essai des textiles sélectionnées, et
- les propriétés de résistance thermique à l'arc, telles que:
a) la caractéristique d'arc des matériaux (ATPV ou EBT50), lorsque vérifiée avec un arc électrique à l'air libre sous des conditions de laboratoire déterminées et conformément à la CEI 61482-1-1, ou
b) la classe de protection à l'arc des matériaux et articles d'habillement (Classe 1 ou Classe 2), lorsque vérifiée avec un arc électrique dirigé et contraint sous des conditions de laboratoire déterminées et conformément à la CEI 61482-1-2.
Les exigences de la présente norme ne traitent pas des dangers d'électrisation. La présente norme est applicable en combinaison avec les normes couvrant ce genre de dangers.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 61482-2 has been prepared by IEC technical committee 78: Live
