25、of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 197-2:2000. This document has been prepared under a mandate given to CEN by the European Commission and the European Free

26、Trade Association. Compared to the version EN 197-2:2000, the following major changes have been made in this document: 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

27、 Directive (Directive 89/106/EEC) (Annex C); link between this European Standard and Annexes ZA of European Standards covering cements; guidance concerning the uncertainty of measurements in the evaluation of test results; numerical criteria for the evaluation procedure for calcium aluminate cement

28、conforming to EN 14647, (Annex A); 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).

BS EN 197-2:2014EN 197-2:2014 (E) 5 1 Scope This European Standard specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements to their corresp

31、onding 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 autocontrol testing of samples, and for the tasks of the product certificat

32、ion body. It also provides rules for actions to be followed in the event of non-conformity, the procedure for the AVCP and requirements for dispatching centres. In this European Standard, the word “cement” is used to refer both to common cements as defined in EN 197-1 and to other cements and binder

33、s for which the relevant product specification standard makes reference to this European Standard and which are submitted for certification. Such a cement is produced at a given factory and belongs to a particular type and a particular strength class, as defined and specified in the relevant product

34、 specification standard. The guidelines given in the Technical Report CEN/TR 14245 11)should be used for the application of this European Standard. This European Standard should be linked with Annexes ZA of European Standards covering cements and binders, i.e. EN 197-1, EN 14216, EN 14647, EN 413-1,

35、 EN 15743, in particular for the assignments of tasks to the manufacturer and to the product certification body. NOTE The reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards. 2 Normative refe
