25、RIC ARC Part 2: Requirements 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 conc
26、erning 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)”). The
27、ir 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
28、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 re
29、levant 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 th
30、e 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 maxim
31、um 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
32、 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 com
33、mittees 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 Publicat
34、ions. 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 pat
35、ent 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 Working. The text of this standard is based on the following documents: FDIS Report on voting 78/783/FDIS 78/797/RVD F
36、ull information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 61482-2 IEC:2009 5 A list of all parts of the IEC 61482 series, published under the
37、general title Live working Protective clothing against the thermal hazards of an electric arc, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under “http:/webstore.
38、iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 61482-2 IEC:2009 INTRODUCTION This International Standard has been prepared in accordance with the requirements of IEC 61477. The produc
39、ts designed and manufactured according to this standard contribute to the safety of the users, provided they are used by skilled persons, in accordance with safe methods of work and the instructions for use. The product covered by this standard may have an impact on the environment during some or al
40、l stages of its life cycle. These impacts can range from slight to significant, be of short-term or long-term, and occur at the global, regional or local level. This standard does not include requirements and test provisions for the manufacturers of the product, or recommendations to the users of th
41、e product for environmental improvement. However, all parties intervening in its design, manufacture, packaging, distribution, use, maintenance, repair, reuse, recovery and disposal are invited to take account of environmental considerations. -,-,- 61482-2 IEC:2009 7 LIVE WORKING PROTECTIVE CLOTHING
42、 AGAINST THE THERMAL HAZARDS OF AN ELECTRIC ARC Part 2: Requirements 1 Scope This part of IEC 61482 is applicable to protective clothing used in work if there is an electric arc hazard. This standard specifies requirements and test methods applicable to materials and garments for protective clothing
43、 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 the arc rating of materials (ATPV or EBT50), when tested with an open electric arc un
44、der defined laboratory conditions according to IEC 61482-1-1, or 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 addr
45、ess electric shock hazards. The present standard is applicable in combination with standards covering such hazards. NOTE 1 If conductive fibres are used in the construction of the garments the risk for electric shock hazard should be considered. This standard does not contain requirements for the pr
46、otection of head, hands and feet. NOTE 2 Requirements and tests to cover these hazards are under development. Requirements of this standard do not cover the electric arc hazards of electric shock, noise, UV emissions, pressure shrapnel, hot oil, the consequences of physical and mental shock and the
47、toxic influences. NOTE 3 The standard is applicable in combination with standards covering such hazards. 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
