3、forewordThis British Standard is the official English language version of EN 10080:2005 but will not become current until 01 January 2006.EN 10080 is a candidate harmonized European Standard and fully takes into account the requirements of the European Commission mandate M115, Reinforcing and prestr

4、essing steel (for concrete), given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 10080 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an

5、announcement in the Official Journal of the European Communities.The Commission in consultation with Member States has agreed a transition period for the co-existence of harmonized European Standards and their corresponding national standard(s). It is intended that this period will comprise a period

6、, usually nine months, after the date of availability of the European Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this co-existence period, conflicting nati

7、onal standard(s) will be withdrawn.EN 10080 does not include all the requirements to fully specify reinforcing steels. It is intended that EN 10080 should be used in conjunction with a Technical Specification, in which the details of the performance characteristics are specified. Within the UK, thre

8、e standards have been revised for use with EN 10080, these are: BS 4449:2005, Steel for the reinforcement of concrete Weldable reinforcing steel Bar, coil and decoiled product Specification BS 4482:2005, Steel wire for the reinforcement of concrete products Specification BS 4483:2005, Steel fabric f

9、or the reinforcement of concrete SpecificationEN 10080:2005 is the subject of transitional arrangements agreed under the Commission mandate. The above standards contain some requirements, which conflict with EN 10080:2005. Based on the transition period of twenty-one months, these standards will be

10、further revised by October 2007, so that they do not conflict with EN 10080.NOTE This date is approximate. Users of this standard should contact BSI Customer Services for confirmation of revisions.Summary of pagesThis document comprises a front cover, an inside front cover, page i, a blank page, the

13、 apply. The significance of the CE marking is that the product manufacturer claims compliance with the harmonized requirements given in the normative text of the product standard. These relate to the essential requirements of the EU Construction Products Directive. Not all product characteristics ne

14、ed necessarily be given on the CE marking, but those product characteristics covered by regulations in force in each EU Member State, where the manufacturer intends that the product will be used, do need to be stated.Cross-referencesThe British Standards which implement international or European pub
