8、ontains terms and definitions relating to telecontrol terminology. The terms and definitions given in this British Standard are technically identical with the corresponding terms appearing in Chapter371 of the International Electrotechnical Vocabulary, published by the International Electrotechnical
9、 Commission (IEC). The glossary is divided into five main Parts, each of which is further 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 make
10、s it possible to add new Groups or revise existing Groups at any time without affecting the remainder of the glossary. The five main 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 p
11、articular 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 respectively form the first two Groups of Part1. General terms par
12、ticular to Part2 and Part3 similarly form the first Groups of their respective Parts. The specialist Groups 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 glo
13、ssary 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. Current usage has therefore been accepted as the authority for terms and their meanings except wh
14、ere 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 terms are in use, those which are deprecated are omitted from the body of the text but are en
15、tered 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 terms are printed in less prominent type to indicate the intention to deprecate them in the co
16、urse of time. Where synonyms are considered of equal value they are shown in the same type. Where terms are used with somewhat different meanings in different branches of electrical engineering, appropriate definitions are given in the Groups of the glossary corresponding to these branches. Such a d
17、efinition, 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 accepted meaning of that term. Under no circumstances should it be regarded as taking the
18、place of a specification.BS4727-2:Group12:1990 BSI 10-1999 iii An effort has been made to arrange the terms in a logical order proceeding from the general to the specific and from the whole to the part and placing allied terms in proximity. Each term has assigned to it a Part number (one digit) and
19、a Group number of two digits followed by a space and four digits, the first digit of which represents the section, the second digit the subsection and the last two digits the place within the subsection. The International Electrotechnical Vocabulary employs a different numbering system and for conve
20、nience the IEV number is given in parentheses after the BS number for each term. A general view of the arrangement of the Group in the glossary can be obtained from the guide to the glossary. An alphabetical index of the terms of the group is provided at the end to facilitate reference to particular
21、 terms. For simplicity, only the last four digits of a terms number are quoted in the index. 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, for Parts 2 and 3, and also togeth
22、er with Groups 01 and 02 of Part1. In this glossary parentheses () enclose words or phrases that are not part of the term or definition and can be omitted without affecting the meaning. Square brackets enclose words which may replace a preceeding part of an expression. A British Standard does not pu
23、rport 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 pages This document comprises a front cover, an inside front
