30、ion (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
31、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 int
32、erested 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
33、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 intereste
34、d 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
35、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 betwe
36、en 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 bodies provide conformity assessment services and, in some areas, access to IEC marks of con
37、formity. 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 IEC or its directors, employees, servants or agents including individual experts and mem
38、bers 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
39、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
40、may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60393-6 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This second edition cancels and replaces the fi
41、rst edition published in 2003 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 assessment level EZ (zero nonconforming); b) complete editorial revision.

42、16IEC 60393-6:2015 IEC 2015 5 The text of this standard is based on the following documents: FDIS Report on voting 40/2409/FDIS 40/2424/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This International Standard
43、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 website. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The
44、 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 publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised
45、 edition, or amended. BS EN 60393-6:2016 6 IEC 60393-6:2015 IEC 2015 POTENTIOMETERS FOR USE IN ELECTRONIC EQUIPMENT Part 6: Sectional specification Surface mount preset potentiometers 1 General 1.1 Scope This part of IEC 60393 applies to surface mount preset potentiometers for use in electronic equi
46、pment. This part of IEC 60393 prescribes preferred ratings and characteristics and selects from IEC 60393-1, the appropriate quality assessment procedures, tests and measuring methods, and it gives general performance requirements for this type of potentiometers. This standard gives the minimum perf
47、ormance requirements and test severities. 1.2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of
48、the referenced document (including any amendments) applies.
