31、d and non-wirewound potentiometers 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 question
32、s 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)”
33、). 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 collabor
34、ates 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 t
35、he 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 th
36、at 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
37、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 itself does not provide any attestation of conformity. Independent certification bod
38、ies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried 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
39、 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
40、 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)
41、 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 60393-5 has been prepared by IEC technical committee 40: Capacitor
42、s and resistors for electronic equipment. This third edition cancels and replaces the second edition published in 1992 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) revision of the information on the a
43、ssessment level EZ and FZ (zero nonconforming); b) complete editorial revision. BS EN 60393-5:2016IEC 60393-5:2015 IEC 2015 5 The text of this standard is based on the following documents: FDIS Report on voting 40/2408/FDIS 40/2423/RVD Full information on the voting for the approval of this standard
44、 can be found in the report on voting indicated in the above table. This International Standard is to be used in conjunction with IEC 60393-1:2008. A list of all parts in the IEC 60363 series, published under the general title Potentiometers for use in electronic equipment, can be found on the IEC w
45、ebsite. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific
46、publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended.

47、 potentiometers 1 General 1.1 Scope This part of IEC 60393 applies to single-turn rotary low-power wirewound and non-wirewound potentiometers, with a rated dissipation less than to 10 W. These potentiometers are primarily intended for use in electronic equipment. This part of IEC 60393 prescribes pr
48、eferred ratings and characteristics and selects from IEC 60393-1, appropriate quality assessment procedures, tests and measuring methods. It provides general performance requirements for this type of potentiometer. This standard gives the minimum performance requirements and test severities. 1.2 Nor
