DIN EN 197-2:2014-05

This European Standard specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements to their corresponding product specification standards, including certification of constancy of performance by a product certification body. The standard provides technical rules for factory production control by the manufacturer, including auto-control testing of samples, and for the tasks of the product certification body. It also provides rules for actions to be followed in the event of non-conformity, the procedure for the assessment and verification of constancy of performance and requirements for dispatching centres. Compared to DIN EN 197-2:2000-11, the following modifications have been made: a) use of the terminology given by the Construction Products Regulation (Regulation (EU) No 305/2011) and comparison with the earlier terminology according to the Construction Products Directive (Directive 89/106/EEC) (Annex C); b) reference to the link between this European Standard and Annexes ZA of European Standards covering cements; c) guidance concerning the uncertainty of measurements in the evaluation of test results; d) numerical criteria for the evaluation procedure for calcium aluminate cement conforming to EN 14647 (Annex A); e) figure describing the procedure for certification of constancy of performance of cement in a new factory or of a new type of cement in an existing factory (Annex B). This standard has been prepared by CEN/TC 51 "Cement and building limes", secretariat NBN, Belgium. The responsible national committee at the Standards Committee Building and Civil Engineering is NA 005-07-13 AA "Zement" ("Cement").
