The work of preparing International Standards is normally carried out through ISO technical commit
9、tees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the In
10、ternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International
11、 Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the

13、vi Avant-propos LISO (Organisation internationale de normalisation) est une fdration mondiale dorganismes nationaux de normalisation (comits membres de lISO). Llaboration des Normes internationales est en gnral confie aux comits techniques de lISO. Chaque comit membre intress par une tude a le droit
14、 de faire partie du comit technique cr cet effet. Les organisations internationales, gouvernementales et non gouvernementales, en liaison avec lISO participent galement aux travaux. LISO collabore troitement avec la Commission lectrotechnique internationale (CEI) en ce qui concerne la normalisation
15、lectrotechnique. Les Normes internationales sont rdiges conformment aux rgles donnes dans les Directives ISO/CEI, Partie 2. La tche principale des comits techniques est dlaborer les Normes internationales. Les projets de Normes internationales adopts par les comits techniques sont soumis aux comits
16、membres pour vote. Leur publication comme Normes internationales requiert lapprobation de 75 % au moins des comits membres votants. Lattention est appele sur le fait que certains des lments du prsent document peuvent faire lobjet de droits de proprit intellectuelle ou de droits analogues. LISO ne sa

LISO 23718 a t labore par le comit technique ISO/TC 164, Essais mcaniques des mtaux. LISO 23718 annule et remplace lISO/TR 12735-1:1996, dont elle constitue une rvision technique. BS ISO
18、23718:2007viiIntroduction This International Standard was prepared to define terms common to mechanical testing of metals in order to help avoid contradictions and misunderstandings among them. Included are only those terms regarded as common to the Technical Committee (TC) and to each Subcommittee
19、(SC). BS ISO 23718:2007viii Introduction La prsente Norme internationale a t prpare pour dfinir les termes communs aux essais mcaniques des mtaux de faon viter des contradictions et des malentendus. On y trouve seulement les termes considrs communs au comit technique (TC) et chaque sous-comit (SC).
