8、y Chapter702:Oscillations, signals and related devices, 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 Germ

9、an, Spanish, Italian, Dutch, Polish, Swedish and Japanese. 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 compl

10、eted. 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 electronics; Part 2: Terms particular to power engine

11、ering; 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 electronics form Groups 01 to 02 of Part 1. The speciali

12、st 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 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

13、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 for terms and their meaning except where there has been a very good reason for doing otherwise, e.g. wh

14、ere 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 alphabetical index with a cross-reference to the stan

15、dard 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 synonyms are considered of equal value they ar

16、e 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 the context of its Group, should if possible b

17、e 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 far as possible the terms are arranged in a lo

18、gical 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 future editions of BS 4727, only the International E

19、lectrotechnical Vocabulary numbering system is used.BS4727-3:Group14:1992 BSI 11-1999 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 provided at the end of each Group to facilitate re

20、ference 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 parentheses ( ) enclose words or phrases that are

21、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 contract. Users of British Standards are responsi

22、ble for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
