9、s Policy Committee and is identical with IEC50(712):1992 International Electrotechnical Vocabulary Chapter712:Antennas, published by the International Electrotechnical Commission (IEC). For ease of production purposes the definitions given in French and Russian have been retained, together with the
10、translation of the terms (but not definitions) given in German, Spanish, Italian, Dutch, Polish and Swedish. The glossary is divided into five Parts, each of which is subdivided into Groups. Each Group will comprise the terms and definitions used in a particular branch of electrical engineering and
11、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 glossary. The five Parts of the glossary are as follows. Part 1: Terms common to power, telecommunications and ele
12、ctronics; 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 particular to electromedical equipment. Fundamental and general terms common to power, telecommunications and electr
13、onics from Groups 01 to 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 subject. As far as has been practical all terms and definitions established in current usage and falling within the scope of this glossary have been i
14、ncluded. 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. Current usage has therefore been accepted as the authority of terms and their meaning except where there has been
15、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 terms are in use, those which are deprecated are omitted from the body of the text but are entered in the alphab
16、etical 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 terms are printed in less prominent type to indicate the intention to deprecate them in the course of time. Where
17、 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 definitions are given in the Groups of the glossary corresponding to these branches. Such a definition, when taken out of
18、 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 accepted meaning of that term. Under no circumstances should it be regarded as taking the place of a specification. As
19、 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 earlier editions of BS 4727, a special national numbering system was used, however, to facilitate publication of futur
20、e editions of BS 4727, only the International Electrotechnical Vocabulary numbering system is used.BS4727-3:Group 15:1992 BSI 10-1999 iii A general view of the position of the Group in the glossary can be obtained from the guide to the glossary. An alphabetical index of the terms of each Group is pr
21、ovided 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 Groups covering general or fundamental terms within the Part and Groups 01 and 02 of Part 1. In this glossary pa
22、rentheses () 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 preceding part of an expression. A British Standard does not purport to include all the necessary provisions of a co
23、ntract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
