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

Ciment - Lignes Directrices pour l’application de l’EN 197-2: Évaluation et vérification de la constance de la performance
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).

European foreword
This document (CEN/TR 14245:2020) has been prepared by Technical Committee CEN/TC 51 “Cement
and building limes”, the secretariat of which is held by NBN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 14245:2014.
Compared with CEN/TR 14245:2014, the following changes have been made:
— The Guidelines Document follows the changes made in EN 197-2;
— Guidance relating to AVCP for distributors and importers has been inserted in the Guidelines
Document.
Introduction to this Guidelines Document
Purpose
The purpose of this document is to provide explanatory detail on points not fully elaborated in
EN 197-2. It is intended for use by all parties involved in the certification of cement following EN 197-2.
It is an objective of this Guidelines Document that its use will assist in the establishment of equivalent
procedures for certification of cement. It is expected that, following this document, traditional good
procedures and practices that can be different can continue to be used, provided that they are not in
contradiction with EN 197-2 and the relevant product specification standard. Such existing good
procedures and practices, applied in conjunction with these Guidelines, are not considered to be an
impediment to the achievement of the uniform level of certification throughout Europe, and by different
product certification bodies.
This document is based on existing situations for production, assessment and verification of constancy
of performance of cements. In case of situations different to those included in this document, specific
procedures should be elaborated on a case by case decision and be fully recorded and approved. These
specific procedures should always fulfil the specifications given in EN 197-1 and EN 197-2 and lead to
the same level of confidence in product that would be achieved by application of this document.
Arrangement
The clause numbering system of EN 197-2 is followed. The text of each of the clauses of the European
Standard is reproduced in full and is followed by guidance, which is provided only for those clauses
where clarification or elaboration is needed.

Annexes A and B
1 Scope
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.
