29、sing 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 Standa

30、rds, 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 prepar

31、atory 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 organiza

32、tions. 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

33、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

34、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 regiona

35、l publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by

36、independent certification bodies. 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

37、 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 Norm

38、ative 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 respo

39、nsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. In exceptional circumstances, a technical committee may propose the publication of a technical specification when the required support cannot be obtained for the pub

40、lication of an International Standard, despite repeated efforts, or the subject is still under technical development or where, for any other reason, there is the future but no immediate possibility of an agreement on an International Standard. Technical specifications are subject to review within th

41、ree years of publication to decide whether they can be transformed into International Standards. This document is being issued in the Technical Specification series of publications (according to the ISO/IEC Directives, Part 1, 3.1.1.1) as a “prospective standard for provisional application” in the f

42、ield of determination of the electrostatic properties of garments and garment materials because there is an urgent need for guidance on how standards in this field should be used to meet an identified need. TS 61340-4-2 IEC:2013 5 This document is not to be regarded as an “International Standard”. I

43、t is proposed for provisional application so that information and experience of its use in practice may be gathered. Comments on the content of this document should be sent to the IEC Central Office. A review of this technical specification will be carried out not later than 3 years after its public

44、ation with the options of: extension for another 3 years; conversion into an International Standard; or withdrawal. IEC 61340-4-2, which is a technical specification, has been prepared by IEC technical committee 101: Electrostatics. The text of this technical specification is based on the following

45、documents: Enquiry draft Report on voting 101/374/DTS 101/388/RVC Full information on the voting for the approval of this technical specification can be found in the report on voting indicated in the above table. The French version of this standard has not been voted upon. This publication has been

46、drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts in the IEC 61340 series, published under the general title Electrostatics, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability dat

47、e indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be transformed into an International Standard, reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the

48、cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this document using a colour printer. 6 TS 61340-4-2 IEC:2013 INTRODUCTION The garments worn by most people in their everyda

49、y lives are not usually designed to dissipate static electricity. Some natural fibres, such as cotton or linen, have sufficient retained moisture to provide some degree of conductivity and may dissipate charge at an acceptable rate. However, synthetic fibres, such as polyester or polyamide, or natural fibres under low humidity conditions are not able to dissipate charge quickly. If el
