EN 1504-7:2006 (E) 3 Foreword This document (EN 1504-7:2006) has been prepared by Technical Committee CEN/TC 104 “Concrete and related products”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2007, and conflicting national standards shall be withdrawn at the latest by December 2008. It has been developed by sub-committee 8 "Protection and repairs of concrete structures" (Secretariat AFNOR). This Part of EN 1504 does not supersede any other European Standard. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association and supports essential requirements of EU Construction Products Directive (89/106/EC).
For the relationship with the EU Directive, see informative Annex ZA, which is an integral part of this document. This Part of EN 1504 includes an informative Annex A, dealing with minimum frequency of testing for factory production control.
