7、al foreword This Group of BS 4727-3 has been prepared by Technical Comittee GEL/1, Terminology, and is identical with IEC 50(801):1994, International Electrotechnical Vocabulary Chapter 801: Acoustics and electroacoustics , published by the International Electrotechnical Commission (IEC). For ease o
8、f production purposes the definitions given in French and Russian have been retained, together with the translation of the terms (but not the definitions) given in German, Spanish, Italian, Dutch, Polish and Swedish. The glossary is divided into five Parts, each of which is subdivided into Groups. E
9、ach Group will comprise the terms and definitions used in a particular branch of electrical engineering and will be issued individually as soon as it is completed. This arrangement makes it possible to add new Groups or review existing Groups at any time without affecting the remainder of the glossa
10、ry. The five Parts of the glossary are as follows. Part 1: Terms common to power, telecommunications and electronics; Part 2: Terms particular to power engineering; Part 3: Terms particular to telecommunications and electronics; Part 4: Terms particular to lighting and colour; Part 5: Terms particul
11、ar to electromedical equipment. Fundamental and general terms common to power, telecommunications and electronics form Groups 01 and 02 of Part 1. The specialist Groups (e.g. Groups 03 to 13 of Part 1) contain only the terms and definitions relating to their subjects. As far as has been practicable
12、all terms and definitions established in current usage and falling within the scope of this glossary have been included. Experience has shown that it is rarely possible to replace, or even to modify, a well established term no matter what the logical or aesthetic shortcomings of that term may be. Cu
13、rrent usage has therefore been accepted as the authority for terms and their meaning except where there has been a very good reason for doing otherwise, e.g. where terms have been considered to be fundamentally wrong, ambiguous, superfluous or in need of standardization. Where two or more synonymous
14、 terms are in use, those which are deprecated are omitted from the body of the text but are entered in the alphabetical index with a cross-reference to the standard term. In cases where it was felt that the time was not yet right to deprecate a synonym, preferred terms are given first and the other
15、terms are printed in less prominent type to indicate the intention to deprecate them in the course of time. Where synonyms are considered of equal value they are shown in the same type. Where terms are used with different meanings in different branches of electrical engineering, appropriate definiti
16、ons are given in the Groups of the glossary corresponding to these branches. Such a definition, when taken out of the context of its Group, should if possible be quoted with a preamble indicating its proper context. It is to be noted that the given definition of a term represents the generally accep
17、ted meaning of that term. Under no circumstances should it be regarded as taking the place of a specification. As far as possible the terms are arranged in a logical order proceeding from the general to the specific and from the whole to the part, and allied terms are placed close together. In earli
18、er editions of BS 4727, a special national numbering system was used, however, to facilitate publication of future editions of BS 4727, only the International Electrotechnical Vocabulary numbering system is used.BS4727-3:Group 08:1995 BSI 09-1999 iii A general view of the position of the Group in th
19、e glossary can be obtained from the guide to the glossary. An alphabetical index of the terms of each Group is provided at the end of each Group to facilitate reference to particular terms. It is recommended that the user of any Group of the glossary should consider the Group in association with the
20、 Groups covering general or fundamental terms within the Part and Groups 01 and 02 of Part 1. In this glossary parentheses ( ) enclose words or phrases that are not part of the terms or definitions and can be omitted without affecting the meaning. Square brackets enclose words which may replace a pr
21、eceding part of an expression. A British Standard does not purport to include all the necessary provisions of 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
