This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements, including certification of constancy of performance.<\/p>\n
The document provides technical rules for factory production control, further testing of samples taken at the manufacturing plant (autocontrol testing) and assessment of the performance of the cement, initial inspection of the manufacturing plant and of factory production control, continuing surveillance, assessment and evaluation of factory production control and audit-testing of samples. It also provides rules for actions to be followed in the event of non-conformity and requirements for depots.<\/p>\n
In this document, the word \u201ccement\u201d is used to refer both to common cements as defined in EN 197?1<\/span><\/span> and to other cements and binders for which the relevant product specification standard makes reference to this document 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.<\/p>\n The guidelines given in the Technical Report CEN\/TR 14245<\/span><\/span> contain information for the application of this document.<\/p>\n This document is linked with Annexes ZA of European Standards covering cements and binders, i.e. EN 197?1<\/span><\/span>, EN 14216<\/span><\/span>, EN 14647<\/span><\/span>, EN 413?1<\/span><\/span> and EN 15743<\/span><\/span>.<\/p>\n The reason for having drafted this separate document is that the provisions it includes are applicable to different products covered by different European Standards.<\/p>\n<\/div>\n EN 197?2<\/span><\/span> deals with the assessment and verification of constancy of performance (AVCP) of cements and binders that are submitted for certification. It deals in particular with cases where \u201cfurther testing\u201d 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<\/span><\/span> is applicable are: the common cement products and the low heat cements and the sulfate resisting cements, refer to EN 197?1<\/span><\/span>, the very low heat special cements, refer to EN 14216<\/span><\/span>, the supersulfated cements, refer to EN 15743<\/span><\/span>, the calcium aluminate cements, refer to EN 14647<\/span><\/span>, and the masonry cements, refer to EN 413?1<\/span><\/span>.<\/p>\n Cement.
