20、mission (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

21、 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 preparation is entrusted to technical committees; any IEC National Committee

22、 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 with the International Organization for Standardization (ISO) in accord

23、ance 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 inte

24、rested 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 respons

25、ible 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

26、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 any equipment declared to be in conformity with an IEC Publication. 6) All

27、 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 for any personal injury, property damage or

28、 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 Normative references cited in this publicati

29、on. 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 responsible for identifying any or all such p

34、fication A blank detail specification is a supplementary document to the generic specification and contains requirements for style and layout and minimum content of detail specifications. Detail specifications not complying with these requirements shall not be considered as being in accordance with

35、IEC specifications nor shall they so be described. In the preparation of detail specifications, the content of 4.1 of the generic specification shall be taken into account. The numbers between brackets on the first page correspond to the following information which shall be inserted in the position

36、indicated. Identification of the detail specification 1 The “International Electrotechnical Commission” or the National Organisation under whose authority the detail specification is drafted. 2 The IEC or National Standards number of the detail specification, date of issue and any other information

37、required by the national system. 3 The number and issue number of the IEC or national generic specification. 4 The IEC number of the blank detail specification. Identification of the thermistor 5 A short description of the type of thermistor. 6 Information on typical construction (if applicable). NO

38、TE When the thermistor is not designed for use on printed boards, this should be stated in the detail specification in this position. 7 Outline drawing with main dimensions which are important for the interchangeability and/or reference to the national or international documents for outlines. Altern

39、atively, this drawing may be given in the annex to the detail specification. 8 Application or group of applications covered and/or assessment level. 9 Reference data on the most important properties, to allow comparison between the various thermistor types. 62319-1-1 IEC:2005 5 Information on the av
