Any divergence between the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter. Preface This standard has been p

20、501:1990 BSI 08-1999 1 Introduction Blank 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. Detail specifications not complying with these requireme

21、nts may not be considered as being in accordance with IEC specifications nor shall they so be described. In the preparation of detail specifications the content of Sub-clause1.4 of the sectional specification shall be taken into account. The numbers between brackets on the first page correspond to t

23、umber of the detail specification, date of issue and any further information 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 capacitor 5 A short description of the t

24、ype of capacitor. 6 Information on typical construction (when applicable). NOTEWhen the capacitor is not designed for use in printed board applications, this shall be clearly stated in the detail specification in this position. 7 Outline drawing with main dimensions which are of importance for inter

25、changeability and/or reference to the national or international documents for outlines. Alternatively, this drawing may be given in an appendix to the detail specification. 8 Application or group of applications covered and/or assessment level. NOTEThe assessment level(s) to be used in a detail spec

26、ification shall be selected from the sectional specification, Sub-clause3.5.4. This implies that one blank detail specification may be used in combination with several assessment levels, provided the grouping of the tests does not change. 9 Reference data on the most important properties, to allow c
