31、tion 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 activities, IEC
32、 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 subject dealt with
33、 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 determined by ag
34、reement 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 Committees. 3) IE
35、C 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 which they are us
36、ed 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 Publication and the c
37、orresponding 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 any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have t
38、he 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 for any personal injury, property damage or other damage of any nature whatsoeve
39、r, 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 Normative references cited in this publication. Use of the referenced publication
40、s 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 responsible for identifying any or all such patent rights. International Standard
41、IEC 60115-8 has been prepared by IEC technical committee 40: Capacitors and resistors for electronic equipment. This second edition cancels and replaces the first edition, published in 1989, and its Amendment 1 (2000). This second edition constitutes a technical revision and includes test conditions
42、 and requirements for lead-free soldering and assessment procedures meeting the requirements of a “zero defect” approach. The major technical changes with regard to the first edition are the following: introduction of a product classification based on application requirements; extension of the list
43、of styles and dimensions; use of an extended scope of stability class definitions; extension of the lists of preferred values of ratings inclusion of test conditions and requirements for lead-free soldering, for periodic overload and for resistance to electrostatic discharge (ESD); 60115-8 IEC:2009
44、5 inclusion of a new set of severities for a shear test; inclusion of definitions for a test board; replacement of assessment level E and possible others by the sole assessment level EZ, meeting the requirements of a “zero defect” approach; inclusion of an extended endurance test, a flammability tes
45、t, a temperature rise test, vibration tests, an extended rapid change of temperature test, and a single pulse high- voltage overload test; inclusion of requirements applicable to 0 resistors (jumpers). This bilingual version (2013-01) corresponds to the monolingual English version, published in 2009
46、-01. The text of this standard is based on the following documents: FDIS Report on voting 40/1933/FDIS 40/1970/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. The French version of this standard has not been vote
47、d upon. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts of the IEC 60115 series, under the general title Fixed resistors for use in electronic equipment, can be found on the IEC website. The committee has decided that the contents of this
48、publication will remain unchanged until the maintenance result 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 edition, or amended. 6 60115-8 IEC:2009
49、 FIXED RESISTORS FOR USE IN ELECTRONIC EQUIPMENT Part 8: Sectional specification Fixed surface mount resistors 1 General 1.1 Scope This part of IEC 60115 is applicable to fixed surface mount resistors for use in electronic equipment. These resistors are typically described according to types (different geometric shapes) and styles (different dimensions). They have metallized t
