9、fundamental terms: The entries are classified in groups to each of which is assigned a four-digit serial number. The first two digits being those of the part of this International Standard. Each entry is assigned a six-digit index number. The first four digits being those of the part of this Interna
10、tional Standard and the group. In order that versions of this International Standard in various languages are related, the numbers assigned to parts, groups and entries are the same for all languages. 2.4 Selection of terms and wording of definitions The selection of terms and the wording of definit
11、ions have, as far as possible, followed established usage. When there were contradictions, solutions agreeable to the majority have been sought. 2.5 Multiple meanings When, in one of the working languages, a given term has several meanings, each meaning is given a separate entry in order to facilita
12、te translation into other languages. 2.6 Abbreviations As indicated in 2.2, abbreviations in current use are given for some terms. Such abbreviations are not used in the texts of the definitions, examples or notes. 2.7 Use of parentheses In some terms, a word or words printed in bold typeface are pl
13、aced between parentheses. These words are part of the com- plete term, but they may be omitted when use of the abridged term in a technical context does not introduce ambiguity. In the text of another definition, example, or note in this International Standard, such a term is used only in its comple
14、te form. 2.3 Classification des articles Chaque partie de la presente Norme internationale recoit un numero dordre a deux chiffres, en commencant par 01 pour le chapitre atermes fondamentauxx. Les articles sont repartis en groupes qui recoivent chacun un numero dordre a quatre chiffres, les deux pre
15、miers chiffres Btant ceux du numero de partie de la presente Norme interna- tionale. Chaque article est rep its particular field of application, or its grammatical form. 2.8 Use of brackets When several closely related terms can be defined by texts that differ only in a few words, the terms and thei
16、r definitions are grouped in a single entry. The words to be substituted in order to obtain the different meanings are placed in brackets, i.e. 1 I, in the same order in the term and in the definition. In order to avoid uncertainty regarding the words to be sub- stituted, the last word that accordin
17、g to the above rule could be placed in front of the opening bracket is, wherever possible, placed inside the bracket and repeated for each alternative. 2.9 Use of terms printed in italic typeface in definitions and use of asterisk A term printed in italic typeface in a definition, an example, or a n
18、ote is defined in another entry in this International Standard, which may be in another part. However, the term is printed in italic typeface only the first time it occurs in each entry. Italic typeface is also used for other grammatical forms of a term, for example, plurals of nouns and participles
19、 of verbs. The basic forms of all terms printed in italic typeface are listed in the index at the end of the part (see 2.11). An asterisk is used to separate terms printed in italic typeface when two such terms are referred to in separate entries and directly follow each other (or are separated only
20、 by a punctua- tion sign). Words or terms that are printed in normal typeface are to be understood as defined in current dictionaries or authoritative technical vocabularies. 2.10 Spelling In the English language version of this International Standard, terms, definitions, examples, and notes are giv
21、en in the spelling preferred in the USA. Other correct spellings may be used without violating this International Standard. 2.11 Organization of the alphabetical index For each language used, an alphabetical index is provided at the end of each part. The index includes all terms defined in the part.
22、 Multiple-word terms appear in alphabetical order under each of their key words. Dans certains articles, les termes definis sont suivis par des expressions imprimees en caracteres normaux et placees entre parentheses. Ces expressions ne font pas partie du term mais indiquent des prescriptions demplo
23、i, precisent un domaine dapplication particulier ou indiquent une forme grammaticale. 2.8 Emploi des crochets Lorsque plusieurs termes Btroitement apparent&s peuvent Qtre definis par des textes presque identiques, a quelques mats p&s, les termes et leurs definitions ont et6 group& en un seul article
24、. Les mots a substituer a ceux qui les precedent pour obtenir les differents sens sont places entre crochets (cest-a- dire I) dans le meme ordre dans le terme et dans la defi- nition. En vue deviter toute incertitude sur les mots B rempla- cer, le dernier mot qui, suivant la regle ci-dessus pourrait
25、 Btre place devant le crochet douverture, est place, si possible, I Iinterieur des crochets et &pet6 a chaque occasion. 2.9 Emploi dans les definitions de termes imprimes en caracteres italiques et de Iasterisque Dans le texte dune definition, dun exemple ou dune note, tout terme imprime en caracter
26、es italiques a le sens defini dans un autre article de la presente Norme internationale, qui peut se trouver dans une autre partie. Cependant le terme est imprime en caracteres italiques uniquement la premiere fois quil appa- rait dans chaque article. Les caracteres italiques sont Bgalement utilises
27、 pour les autres formes grammaticales du terme, par exemple, les noms au plu- riel et les verbes au participe. La liste des formes de base de tous les termes imprimes en caracteres italiques est fournie dans Iindex a la fin de la partie (voir 2.11). Lasterisque sert a &parer les termes imprimes en c
28、aracteres italiques quand deux termes se rapportent a des articles &par&s et se suivent directement (ou bien sont &pares simplement par un signe de ponctuation). Les mots ou termes imprimes en caracteres normaux doivent 6tre compris dans le sens qui leur est don& dans les dictionnai- res courants ou
29、 vocabulaires techniques faisant autorite. 2.10 Mode decriture et orthographe Dans la version anglaise de la presente Norme internationale, les termes, definitions, exemples et notes sont Bcrits suivant Iorthographe prevalant aux l?tats-Unis. Dautres or-thographes correctes peuvent etre utilisees sa
