15、r the direction of the Electronic Components Standards Committee, is the generic specification for custom-built capacitors and capacitor modules in the BS9000 system of standards for electronic parts of assessed quality. A British Standard does not purport to include all the necessary provisions of
16、a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi to iv, pages1to20 and a back cover
17、. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.iv blankBS9100:1983 BSI 12-1999 1 0 Introduction This BritishStandard is the generic specification for custom-built capacitors and c
18、apacitor modules which are not appropriate for assessment under qualification approval for one or more of the following reasons. a) Each type is designed for a particular customer requirement. b) Each type requires an individual specification to satisfy the particular customers needs. c) The custome
19、r requirement cannot be satisfied from a standard range capable of qualification approval. Capacitors in these categories are termed custom-built capacitors. Examples of custom-built capacitors are those having package and/or fixing and termination arrangements peculiar to a particular customers app
20、lication or capacitors requiring a specialized process to achieve a particular customer functional requirement, etc. Section 1. Principles and mandatory procedures 1.1 General matters 1.1.1 Scope. This specification gives details of the general requirements, test procedures and other information rel
21、ating to the capability approval of manufacturers of custom-built capacitive units. The units included in the definition of the capability for which approval is sought may have either a single or multi-capacitor function, as described in1.1.1.1 and1.1.1.2. 1.1.1.1 Custom-built capacitors. This stand
22、ard covers custom-built capacitors of the following types. a) Types performing a single capacitive function and manufactured using one or more capacitive elements (see1.1.3.1) permanently electrically interconnected such that only one pair of lead-outs (see1.1.3.2) is available for circuit connectio
23、n and electrical test purposes. b) Types performing only a capacitive function, even when incorporating any add-on component (see1.1.3.3). 1.1.1.2 Custom-built capacitor modules. This standard covers custom-built capacitor modules of the following types. a) Assemblies of capacitors performing a mult
24、i-capacitive function and manufactured using two or more capacitors or capacitive elements, permanently electrically interconnected such that sufficient lead-outs are available to allow measurement of all specified capacitive functions of the module for circuit connection and electrical test purpose

For the purposes of this BritishStandard, the definitions given in BS4727 apply together with the following. 1.1.3.1 capacitive elem
31、ent. An element that is either: a) a BS9000 or BS CECC qualification approved capacitor; or b) a part-manufactured capacitor falling within the boundaries and technologies of the manufacturers own declared capability approval. 1.1.3.2 lead-outs. Any electrical connections that are available for circ
32、uit connection and electrical test purposes. 1.1.3.3 add-on components. Components other than capacitors that are essential to the customer requirements that do not change the capacitive function of the item. Such components shall be permanently attached to the assembly both mechanically and electri
33、cally. They are acceptable for incorporation only when procured in accordance with 3.3 of BS9000-5:1989. 1.1.4 Letters, symbols, signs and abbreviations. The letters, symbols, signs and abbreviations which are employed in all documents applicable to electronic components covered by this specificatio
34、n shall be in conformity with BS5775 or shall be derived in accordance with the principles of that standard. 1.1.5 Graphical symbols. The graphical symbols which are employed in all documents applicable to electronic components covered by this specification shall be in accordance with BS3939 or shal
35、l be derived in accordance with the principles of that standard. 1.1.6 Marking of the component and package 1.1.6.1 Each custom-built capacitor or capacitor module shall be marked with a) and b) and with as many of the remaining items, in the order given below, as is practicable. a) Polarity (electr
