12、ssessment level D/DZ) 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 questions concerning
13、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)”). Their prep
14、aration 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 collaborates closely
15、 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 the relevant
16、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 that the techn
17、ical 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 maximum exte
18、nt 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for an
19、y equipment declared to be in conformity with an IEC Publication. 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
20、 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 Publications. 8
21、) 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 of patent rig
22、hts. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60939-2-1 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. The text of this standard is based on the following documents: FDIS Report on
23、 voting 40/1466/FDIS 40/1487/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.

26、lank detail specification A blank detail specification is a supplementary document to the sectional specification and contains requirements for style and layout and minimum content of detail specifications. In the preparation of detail specifications, the content of 1.4 of the sectional specificatio
27、n shall be taken into account. The use of IEC 60939-2-2 may be more appropriate for components where approval and requalification tests contribute considerably to the cost of the product, whereas the employment of this specification may be necessary for components manufactured in mass production. Th
28、is specification offers the assessment levels D and DZ (Zero defect). Identification of the detail specification and of the component The first page of the detail specification should have the layout recommended on the next page of this blank detail specification. The numbers between square brackets
29、 correspond to the following information which shall be inserted at the position indicated: 1 The name of the National Standards Organization under whose authority the detail specification is published and, if applicable, the organization from which the detail specification is available. 2 The IECQ

Alternatively the drawing may be given in an annex to the deta
33、il specification, but 7 should always contain an illustration of the general outer appearance of the component. 8 The level(s) of quality assessment covered by the detail specification, as appropriate. 9 Reference data giving information on the most important properties of the component which allow
34、comparison between the various component types intended for the same or similar applications. 60939-2-1 IEC:2004(E) 5 1 IEC 60939-2-1-XXX 2 QC XXXXXXXXX ELECTRONIC COMPONENTS OF ASSESSED QUALITY IN ACCORDANCE WITH: IEC 60939-1 IEC 60939-2 3 4 Outline and dimensions: ( . angle projection) PASSIVE FIL
