Bibliography

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 autocontrol 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 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 binders 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 specification standard.The guidelines given in the Technical Report CEN/TR 14245 [1] ) 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, EN 15743, in particular for the assignments of tasks to the manufacturer and to the product certification body.NOTEThe reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards.GuidanceEN 197-2 deals with the evaluation of conformity of cements and binders that are submitted for certification. It deals in particular with cases where “further testing” of the product is undertaken, as is the case for attestation system 1+ under the Construction Products Regulation. The products for which EN 197-2 is applicable are: the common cement products and the low heat cements and the sulfate resisting cements, refer to EN 197-1, the very low heat special cements, refer to EN 14216, the supersulfated cements, refer to EN 15743, the calcium aluminate cements, refer to EN 14647, and the masonry cements, refer to EN 413 1.
