19、ldwide 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 addition to other

20、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 interested in the sub

21、ject 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 with conditions de

22、termined 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 interested IEC National Com

23、mittees. 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 for the way in whi

24、ch 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 between any IEC Publica

25、tion 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 conformity. IEC is no

26、t 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 members of its techni

27、cal 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 or any other IEC P

28、ublications. 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 may be the subject

29、 of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60063 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This third edition cancels and replaces the second edition publishe

30、d in 1963 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: revision of the information on a relationship between an E Series and the tolerance of a resistance or capacitance value of a respective component;

31、introduction of advice on a possible deduction from the marking of a component to an associated E Series and also to an associated tolerance; complete editorial revision. BS EN 60063:2015 4 IEC 60063:2015 IEC 2015 The text of this standard is based on the following documents: FDIS Report on voting 4

32、0/2340A/FDIS 40/2370/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 publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The committee has decided that the contents of this public

33、ation 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 revised edition, or amended. BS EN 60063:2015IEC 60063:2015 IEC

34、 2015 5 PREFERRED NUMBER SERIES FOR RESISTORS AND CAPACITORS 1 Scope This International Standard provides series of preferred values for the resistance of resistors and for the capacitance of capacitors. The definition of such series with a defined numeric resolution is a basic prerequisite for the

35、marking and coding of capacitors and resistors with their respective capacitance or resistance values as described in IEC 60062. NOTE The number series defined in this standard are based on progressive ratios of r10 , with r = 3 2i, and i being a whole number in the range of 0 to 6, hence e.g. of 12

36、10 . This system of progressive ratios had been established prior to the 1952 release of the first edition of this standard1as a consequence of the standardisation of tolerances at 5 %, 10 % and 20 % and the related commercial practice. An adoption of the ISO practice, based on a 1010 system, was ne

37、ver considered achievable. 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 the referenced do

38、cument (including any amendments) applies. IEC 60062, Marking codes for resistors and capacitors 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 E series infinite series of numeric values with a given number of elements per decade, rounded or

39、 derived from the elements of a geometric series Note 1 to entry: The number of elements within a decade, r, is given in the designation of the E series, Er, e.g. E24 for a number series with 24 values per decade. 4 Number series 4.1 Number series with two significant digits The series E24, E12, E6

40、and E3 with two significant digits are the decimal multiples and sub-multiples of the respective values given in Table 1. _ 1IEC 60063:1952, Series of preferred values and their associated tolerances for resistors and capacitors BS EN 60063:2015 6 IEC 60063:2015 IEC 2015 Table 1 Number series with t

42、rs ( )nv2410= where v is a value of the E24 series, and n is a whole positive or negative number. NOTE The values of the E24 series in the range of 27 through 47, and the value 82, divert from the exact mathematical rule. However, a correction of this deviation has never seemed appropriate in light

43、of the historical relevance of this series, having been established prior to the 1952 release of the first edition of this standard. The E12 series is derived from the E24 series by omitting every second term, and likewise is the E6 series derived from the E12 series and the E3 series derived from t

44、he E6 series by omitting every second term thereof. 4.2 Number series with three significant digits The series E192, E96 and E48 with three significant digits are the decimal multiples and sub-multiples of the respective values given in Table 2.
