Cement - Guidelines for the application of EN 197-2: Assessment and verification of constancy of performance

Edition date: 2020-03-11
In Force
Available languages: French, English
Summary: This document specifies the scheme for the assessment and verification of constancy of performance (AVCP) of cements, including certification of constancy of performance. 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. In this document, 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 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. The guidelines given in the Technical Report CEN/TR 14245 contain information for the application of this document. This document is linked with Annexes ZA of European Standards covering cements and binders, i.e. EN 197 1, EN 14216, EN 14647, EN 413 1 and EN 15743. 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. Guidance EN 197 2 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 “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.

Le présent document spécifie le système d’évaluation et de vérification de la constance des performances (EVCP) des ciments, qui inclut une certification de la constance des performances. Ce document fournit les règles techniques pour le contrôle de la production en usine, les essais complémentaires sur des échantillons prélevés dans l’établissement de fabrication (essais d’autocontrôle) et l’évaluation des performances du ciment, l’inspection initiale de l’établissement de fabrication et du contrôle de la production en usine, la surveillance, l’évaluation et l’appréciation permanentes du contrôle de la production en usine et les essais par sondage des échantillons. Il établit également des règles à suivre en cas de non-conformité et les exigences applicables aux centres de distribution et aux dépôts. Dans le présent document, le terme « ciment » est utilisé pour faire référence aux ciments courants tels que définis dans l’EN 197-1 ainsi qu’aux autres ciments et liants dont les normes de spécification de produit correspondantes font référence au présent document et qui sont soumis à certification. Un tel ciment est produit dans une usine donnée et appartient à un type et à une classe de résistance particuliers, définis et spécifiés dans la norme de spécification de produit correspondante. Les lignes directrices données dans le Rapport technique CEN/TR 14245 contiennent des informations sur l’application du présent document. Ce document est lié aux annexes ZA des normes européennes concernant les ciments et les liants, à savoir les normes EN 197-1, EN 14216, EN 14647, EN 413-1 et EN 15743. NOTE La raison pour laquelle ce document séparé a été rédigé est que les dispositions qu’il contient sont applicables à différents produits couverts par des Normes européennes différentes. Lignes directrices L’EN 197-2 traite de l'évaluation et de la vérification de la constance des performances (EVCP) des ciments et des liants qui sont soumis à certification. Elle traite en particulier des cas dans lesquels des « essais complémentaires » du produit sont entrepris, comme c'est le cas pour le système d'attestation 1+ prévu par le règlement sur les produits de construction. Les produits pour lesquels l’EN 197-2 s'applique sont : les ciments courants, les ciments à faible chaleur d'hydratation et les ciments résistants aux sulfates (voir l’EN 197-1), les ciments spéciaux à très faible chaleur d'hydratation (voir l’EN 14216), les ciments sursulfatés (voir l’EN 15743), les ciments d'aluminate de calcium (voir l’EN 14647), ainsi que les ciments à maçonner (voir l’EN 413-1).
