26、4 IEC 61340-2-1:2015 IEC 2015 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ ELECTROSTATICS Part 2-1: Measurement methods Ability of materials and products to dissipate static electric charge FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization

27、 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

28、 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

29、 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 o

30、rganizations. 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 f

31、orm 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 misinterpre

32、tation 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

33、regional 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

34、out by 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 Committ

35、ees 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 t

36、he 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 hel

37、d responsible for identifying any or all such patent rights. International Standard IEC 61340-2-1 has been prepared by IEC technical committee 101: Electrostatics. This second edition cancels and replaces the first edition published in 2002. This edition constitutes a technical revision. This editio

38、n includes the following significant technical changes with respect to the previous edition: BS EN 61340-2-1:2015IEC 61340-2-1:2015 IEC 2015 5 a) the first edition supported requirements in IEC TR 61340-5-1, but with the revision of IEC TR 61340-5-1 into an International Standard, this support is no

39、 longer required; references to IEC 61340-5-111have been removed; b) the introduction gives additional information on when charge decay time measurements are appropriate, and the applications for which each of the two test methods are best suited; c) procedures for performance verification of measur

40、ing instruments for the corona charging method have been added. The text of this standard is based on the following documents: CDV Report on voting 101/446/CDV 101/462/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above tab

41、le. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. It has the status of a horizontal standard in accordance with IEC Guide 1083. A list of all the parts in the IEC 61340 series, published under the general title Electrostatics, can be found on the IEC website. T

42、he committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revise

43、d edition, or amended. _ 1Numbers in square brackets refer to the Bibliography. BS EN 61340-2-1:2015 6 IEC 61340-2-1:2015 IEC 2015 INTRODUCTION Measurements of the rate of dissipation of static charge belong to the essential measurement techniques in the field of electrostatics. For homogeneous cond

44、uctive materials, this property can be evaluated indirectly by measuring resistance or resistivity parameters. Care should be exercised when determining the homogeneity of materials, as some materials that appear homogenous do exhibit non-homogeneous electrical characteristics. If the homogeneity of

45、 materials is not known and cannot be otherwise verified, resistance measurements may not be reliable or may not give enough information. Resistance measurements may also not be reliable when evaluating materials in the dissipative or insulative range and especially for high ohmic materials includin

46、g conductive fibres (e.g. textiles with a metallic grid). In such cases, the rate of dissipation of static charge should be measured directly. BS EN 61340-2-1:2015IEC 61340-2-1:2015 IEC 2015 7 ELECTROSTATICS Part 2-1: Measurement methods Ability of materials and products to dissipate static electric

47、 charge 1 Scope This part of IEC 61340 describes test methods for measuring the rate of dissipation of static charge of insulating and static dissipative materials and products. It includes a generic description of test methods and detailed test procedures for specific applications. The two test met

48、hods for measuring charge decay time, one using corona charging and one using a charged metal plate are different and may not give equivalent results. Nevertheless, each method has a range of applications for which it is best suited. The corona charging method is suitable for evaluating the ability

49、of materials, e.g. textiles, packaging, etc., to dissipate charge from their own surfaces. The charged metal plate method is suitable for evaluating the ability of materials and objects such as gloves, finger cots, hand tools, etc. to dissipate charge from conductive objects placed on or in contact with them. The charged plate method may not be suitable for evaluating the ability of materials to dissipate charge from their own surfaces. In addition to its general appli
