EN 13747 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M/100, Pr
3、ecast Concrete Products, given under the EU Construction Products Directive (89/106/EEC), and is intended to lead to CE marking. The date of applicability of EN 13747 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an anno
4、uncement 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, u
5、sually 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, the national standa
6、rd(s) will be withdrawn. EN 13747 is the subject of transitional arrangements agreed under the Commission mandate. In the UK, there are no corresponding national standards.
