16、00 Foreword This group of Part 2 of this British Standard Glossary, prepared under the authority of the Electrical Industry Standards Committee and the Telecommunication Industry Standards Committee contains terms and definitions relating to tariffs and supersedes Sub-section 56 of BS 205, Glossary
17、of terms used in electrical engineering, Part 4. The terms and definitions are in close agreement with the corresponding terms in the latest edition of the International Electrotechnical Vocabulary prepared by the International Electrotechnical Commission (IEC). In this new glossary a number of sign
18、ificant changes have been introduced. It has been decided to combine into one glossary the subjects previously covered by BS 204, Glossary of terms used in telecommunications (including radio) and electronics, BS 205, BS 233, Glossary of terms used in illumination and photometry, and BS 1611, Glossa
19、ry of colour terms used in science and industry. The glossary is divided into four main parts, each of which is further sub-divided 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
20、completed. This arrangement makes it possible to add new groups, or revise existing groups, at any time without affecting the remainder of the glossary. The four main parts of the glossary are as follows: Part 1: Terms common to power, telecommunications and electronics; Part 2: Terms particular to
21、power engineering; Part 3: Terms particular to telecommunications and electronics; Part 4: Terms particular to lighting and colour. As groups of terms within the new framework are published, the corresponding parts of the British Standard glossaries mentioned above will be withdrawn. Ultimately the
22、new glossary will replace these standards completely and they will then be withdrawn. Fundamental and general terms common to power, telecommunications and electronics, respectively form the first two groups of Part 1. General terms particular to Part 2, and Part 3 similarly form the first groups of
23、 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 glossary have been included. Experience has shown that it is rar
24、ely 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 where there has been a very good reason for doing otherwise, as
25、 for example, 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 alphabetical index with a cross refer
26、ence 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 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 v
27、alue 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 definition when taken out of the context of its group s
28、hould always be quoted with a preamble indicating its proper context. Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 30 05:55:18 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 4727-2:Group 07:1973 BSI 03-2000iii It is to be noted that the given definition of a term represents the generally accep
29、ted meaning of that term. Under no circumstances should it be regarded as taking the place of a specification. 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 within a sub
30、-section or section of the group. Each term has assigned to it a Part number (one digit) and 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 sub-section, and the last two digits the place within the sub-section.
31、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 terms. For simplicity, only the last four digits of a terms number are quoted in
32、 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 together with Groups 01 and 02 of Part 1. In this glossary square brackets enclose words
33、 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 with a British Standard does not of itself confer immunity from legal
34、obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i to iv, pages 1 to 8 and a back cover.
