35、rising 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 Stan

36、dards, 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 prep

37、aratory 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 organi

38、zations. 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 o

39、f 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 misinterpretatio

40、n 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 regio

41、nal 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 b

42、y 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 f

43、or 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 No

44、rmative 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 res

45、ponsible for identifying any or all such patent rights. International Standard IEC 60062 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This sixth edition cancels and replaces the fifth edition published in 2004 and constitutes a technical revisio

46、n. This edition includes the following significant technical changes with respect to the previous edition: g120 introduction of the new code colour pink for the coding of the multiplier 10-3; g120 introduction of new subclauses, 3.2 Prescription of code colours, 3.3 Methods for marking resistance va

47、lue and tolerance, 3.4 Methods for TCR marking, for improved clarity, the subjects of colour assignment, coding of R value and tolerance, and coding of TCR is dealt with in separate clauses; g120 inclusion of illustrations for TCR marking by interrupted colour band; g120 inclusion of a new subclause

48、 on a fixed length code marking, fixed length code marking of resistance values with up to 3 significant digits, hence a fixed code length of 4 digits, and BS EN 60062:2016BS EN 60062:2016IEC 60062:2016 IEC 2016 6 IEC 60062:2016 IEC 2016 5 fixed length code marking of capacitance values with up to 2

49、 significant digits, hence a fixed code length of 3 digits; g120 introduction of two new clauses, Clause 6, Coding of properties specific to capacitors and Clause 7, Coding of properties specific to resistors; g120 introduction of Annex A, Special three character coding of resistance value with three significant numerals.
