7、ems 123 Index 129BS4727-3:Group 13:1992 ii BSI 02-2000 National foreword This Group of BS 4727-3 has been prepared under the direction of the General Electrotechnical Standards Policy Committee and is identical with IEC50(731):1991 International Electrotechnical Vocabulary Chapter 731: Optical fibre

8、 communication, 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 translation of the terms (but not the definitions) given in German, Spanish, Italian, Dutch, Polish and

9、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 will be issued individually as soon as it is completed. This arrangement makes it possible to add ne

10、w 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 electronics; Part 2: Terms particular to power engineering; Part 3: Terms particular to telecommunicati

11、ons 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 electronics from Groups 01 and 02 of Part 1. The specialist Groups (e.g.Groups03 to 13 of Part 1) contain

12、only the terms and definitions relating to their subject. As far as has been practicable 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 esta

13、blished term no matter what the logical or aesthetic shortcomings of that term may be. Current 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

14、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 alphabetical index with a cross-reference to the standard term. In cases where it was felt that the time

15、 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 synonyms are considered of equal value they are shown in the same type. Where terms are used with

16、 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 the context of its Group, should if possible be quoted with a preamble indicating its proper cont

17、ext. 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 far as possible the terms are arranged in a logical order proceeding from the general to the spec

18、ific 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 future editions of BS 4727, only the International Electrotechnical Vocabulary numbering system is used

19、.BS4727-3:Group 13:1992 BSI 02-2000 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 provided at the end of each Group to facilitate reference to particular terms. It is recommended tha

20、t 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 with 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

21、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 contract. Users of British Standards are responsible for their correct application. Compliance

22、 with a British Standard does not of itself confer immunity from legal obligations.
