    14、 55 1 BST BS*4727:PT5: GR*OL 85 I Lb24669 OLLB035 B I BS 4727 : Part 5 : Group O1 : 1985 Foreword This Group of Part 5 of BS 4727, prepared under the direction of the Health Care Standards Committee, contains terms and definitions relating to radiology and radiological physics. It supersedes BS 2597

    15、 : 1955 which is withdrawn. The terms and definitions given in this British Standard Glossary are technically identical with the corresponding terms appearing in IEC Publication 50(881) : 1984 which is an advance edition of Chapter 881 of the International Electrotechnical Vocabulary. The glossary i

    16、s 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 makes it possible to add new Groups o

    17、r 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 particular to telecommunications and Pa

    18、rt 4 Terms particular to lighting and colour Part 5 Terms particular to electromedical equipment Fundamental and general terms common to power, telecom- munications and electronics respectively form the first two Groups of Part 1. General terms particular to Part 2 and Part 3 similarly form the firs

    19、t 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 glossary have been included. Experience has shown tha

    20、t 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 where there has been a very good reason for doing ot

    21、herwise, 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 alphabetical index with a cross-refer

    22、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

    23、alue they are shown in the same type. electronics Where terms are used with somewhat different meanings in different branches of electrical engineering, appropriate definitions are given in the Groups of the glossary corres- ponding to these branches. Such a definition, when taken out of the context

    24、 of its Group, should always 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. An effort has been

    25、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 a Group number of two digits followed by a space and four digits, the first digit

    26、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 convenience the IEV number is given in parentheses after the BS number for each term. A

    27、 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

    28、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 O1 and 02 of Part I. In this glossary parentheses ( ) enclose words

    29、 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 preceding part of an expression. Attention is drawn to BS 6641 which includes some of the termsappearing in this Groupof Part 5 of BS 4727. BS 6

    30、641 has a specialized purpose, namely to provide definitions of radiological terms which are used in British Standards which form Sections of BS 5724. Whereas BS 4727 reflects current usage of the terms listed, BS 6641 contains some terms which are at present relatively unfamiliar. Differences betwe

    31、en definitions in the two British Standards are mainly editorial but some are technical. In case of difference, the definitions given in BS 6641 are to be preferred for use in connection with BS 5724. Compliance with a British Standard does not of itself confer immunity from legal obligations. 2 BSI
