It is identical with IEC 384-7-1:1991 (QC 300901) “Fixed capacitors for use in electronic equipment. Part 7: Blank detail specification for fixed polystyrene film dielectric metal foil d.c. capacitors. Assessment Level E”, published by the International Electrotechnical Commission (IEC), and is a harmonized specification in the IECQ System of quality assessment for electronic components. IEC 384-7-1 was prepared by IEC Technical Committee No. 40, Capacitors and resistors for electronic equipment, and the United Kingdom participation in the drafting was provided by Subcommittee ECL/4/4, Capacitors and electromagnetic suppression components for electronic equipment, under the direction of Technical Committee ECL/4, Capacitors and resistors for electronic equipment. Scope. This standard lists the ratings, characteristics and inspection requirements which shall be included as mandatory requirements in accordance with BS QC 300900 in any detail specification for these components. The British Standard which implements the IECQ Rules of Procedure is BS 9000 “General requirements for a system for electronic components of assessed quality”. Part 3:1991 “Specification for the national implementation of the IECQ System”. Detail Specifications. Detail Specifications shall comply with the requirements of this Blank Detail Specification and BS QC 001002:1991 “Rules of Procedure of the IEC Quality Assessment System for Electronic Components (IECQ)”. Foreword 1) The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the National Committees having a special interest therein are represented, express, as nearly as possible, an international consensus of opinion on the subjects dealt with. 2) They have the form of recommendations for international use and they are accepted by the National Committees in that sense. 3) In order to promote international unification, the IEC expresses the wish that all National Committees should adopt the text of the IEC recommendation for their national rules in so far as national conditions will permit. Any divergence between the IEC recommendation and the corresponding national rules should, as far as possible, be clearly indicated in the latter.

Detail specifications not complying with these requirements 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-clause 1.4 of the sectional 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 indicated: Identification of the detail specification (1) The “International Electrotechnical Commission” or the National Standards 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 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 type of capacitor. (6) Information on typical construction (if 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 interchangeability 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 specification shall be selected from the sectional specification, Sub-clause 3.5.4. 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 comparison between the various capacitor types.
