The work of preparing International Standards is normally
11、 carried out through ISO technical committees. 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 w
12、ork. ISO collaborates closely with the International 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 Int
13、ernational Standards. Draft International 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
14、the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 16020 was prepared by Technical Committee ISO/TC 17, Steel, Subcommittee SC 16, Steels for the reinforcement and prestressing of concrete. iv BS ISO
15、 16020:2005Introduction The purpose of this International Standard is to promote the worldwide use of common terms in the field of steel for reinforcing and prestressing. The terms and definitions reflect current practice. However, since the coiled hot-rolled ribbed reinforcing steels have come into
16、 the market there has been a lack of consistency in the use of some terms. This applies to wire and bar in particular, and it is hoped that this International Standard will help to establish a more consistent use of these terms. Annex A gives a schematic illustration of the production of reinforcing
17、 steel. v BS ISO 16020:2005blank1Steel for the reinforcement and prestressing of concrete Vocabulary Aciers pour larmature et la prcontrainte du bton Vocabulaire 1 Scope This International Standard defines terms and symbols to be used in the field of reinforcing and prestressing steel for concrete.
18、NOTE In addition to terms in English and French (two of the three official ISO languages), this International Standard gives the equivalent terms in German, Spanish and Norwegian; these are published under the responsibility of the member bodies for Germany (DIN), Spanish (AENOR) and Norway (SN). Ho
19、wever, only the terms and definitions given in the official languages can be considered as ISO terms and definitions. 1 Domaine dapplication La prsente Norme internationale dfinit des termes et symboles utiliser dans le domaine des aciers pour larmature et la prcontrainte du bton. NOTE En complment
20、des termes en anglais et franais (deux des trois langues officielles de lISO), la prsente Norme internationale donne les termes quivalents en allemand, espagnol et norvgien; ces termes sont publis sous la responsabilit des comits membres allemand (DIN), espagnol (AENOR) et norvgien (SN). Toutefois,
21、seuls les termes et dfinitions donns dans les langues officielles peuvent tre considrs comme tant des termes et dfinitions de lISO.
