(Main)Cement - Guidelines for the application of EN 197-2 Conformity Evaluation
Cement - Guidelines for the application of EN 197-2 Conformity Evaluation
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]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.
Zement - Leitlinien für die Anwendung von EN 197-2 Konformitätsbewertung
Diese Europäische Norm legt das Verfahren für die Bewertung und Überprüfung der Leistungsbeständigkeit (en: assessment and verification of constancy of performance (AVCP)) von Zementen nach den ent-sprechenden Produktnormen einschließlich der Zertifizierung der Leistungsbeständigkeit durch eine Produkt-zertifizierungsstelle fest.
Die Norm enthält technische Regeln für die werkseigene Produktionskontrolle durch den Hersteller, einschließlich der internen Überwachungsprüfungen von Proben, und für die Aufgaben der Produktzertifizierungsstelle. Sie enthält darüber hinaus Regeln für Maßnahmen, die bei Nichtkonformität zu ergreifen sind, sowie das Verfahren für die Bewertung und Überprüfung der Leistungsbeständigkeit und Anforderungen für Auslieferungsstellen.
In dieser Europäischen Norm verweist das Wort „Zement“ sowohl auf Normalzemente, wie in EN 197-1 festgelegt, als auch auf weitere Zemente und Bindemittel, deren entsprechende Produktnormen auf diese Europäische Norm verweisen und die der Zertifizierung unterworfen werden. Solch ein Zement wird in einem bestimmten Werk hergestellt und gehört zu einer bestimmten Art und Festigkeitsklasse, wie in der zugehörigen Produktnorm definiert und festgelegt.
Für die Anwendung dieser Europäischen Norm sollte die im Technischen Bericht CEN/TR 14245 1 ) gegebene Anleitung verwendet werden.
Diese Europäische Norm sollte mit dem Anhang ZA von Europäischen Normen, die Zemente und Bindemittel behandeln, d. h. EN 197 1, EN 14216, EN 14647, EN 413 1 und EN 15743, verknüpft werden, insbesondere im Hinblick auf die Zuweisung von Aufgaben für den Hersteller und die Produktzertifizierungs¬stelle.

Introduction to this Guidelines Document
Purpose
The purpose of this Guidelines Document is to provide explanatory detail on points not fully elaborated in
EN 197-2. It is intended for use by manufacturers and by product certification bodies involved in the
certification of cement following EN 197-2, in particular for the issuing of an EC certificate of constancy of
performance.
This document does not deal with the necessary internal procedures that the product certification bodies will
have.
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 may 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, that is
expected from the application of EN 197-2 together with these Guidelines.
This Guidelines Document is based on existing situations for production, evaluation of conformity and
certification of cements. It may happen that product certification bodies be confronted by a situation different
to those included in this document. In such a case, specific procedures should be elaborated on a case by
case situation and be approved and fully recorded by the product certification body. These specific procedures
should always fulfil the requirements of EN 197-1 and EN 197-2 and lead to the same level of confidence in
product conformity that would be achieved by application of this Guidelines 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.

1 Scope
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.
1)
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.
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 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.

CEN/TR 14245:2014 (E)
Guidance
According to EN 197-1:2014, Clause 4, common cements (CEM cements) consist of different materials
and are statistically homogeneous in composition resulting from quality assured production and material
handling processes. A high degree of uniformity in all cement properties is obtained through continuous
mass production processes, in particular, adequate grinding and homogenization processes. Similar
considerations apply for other cements.
Three categories of “factory” are recognized:
— traditional full cement factories, where clinker and cement are produced on the same site;
— grinding plants, where cement is produced by grinding supplied cement constituents;
— blending plants, where ground cement constituents, which may be received already combined as cement,
are blended to produce finished cement.
The following operating steps, which apply for all of these types of factory, are essential in the
manufacturing process. These steps are needed to ensure the necessary uniformity, continuity and
suitability of the cement properties as well as the ability to meet the other requirements of the relevant
product specification standard:
— use of separate and adequate storage for the cement constituents;
— Controlling the cement constituents – including, where relevant, their fineness and particle size
distribution, and therefore their grinding – to achieve a performance of the cement compatible with the
requirements of the product specification standard;
— proportioning the cement constituents in order to achieve the target composition of the cement;
— homogenization of the cement constituents by grinding, or by mixing where relevant;
— storage of finished product, in silos of adequate capacity, allowing proper identification of mass quantities
of product and giving the possibility of taking spot samples at any time without prior notice.
Factories can only be operated by manufacturers which have personnel with sufficient experience and
knowledge in all operating steps important for cement quality and which have the people, test procedures
and test equipment to test, evaluate and correct the cement being produced. The definition of factory in
EN 197-2 takes it, therefore, for granted that all operating steps listed above are carried out in effect
under the same quality responsibility.
3.9
new factory
factory which is not already producing cement(s) certified using this European Standard
3.10
existing factory
factory which is already producing cement(s) certified using this European Standard
3.11
depot
bulk cement handling facility (not located at the factory) used for the dispatch of cement (whether in bulk or
bagged) after transfer or storage where the manufacturer has full responsibility for all aspects of the quality of
the cement

CEN/TR 14245:2014 (E)
Guidance
It is important to point out the difference between a depot and a dispatching centre. The difference
consists essentially of the linkage to the factory and the responsibility for the quality of the cement. In the
case of a depot the facility is strictly linked to the factory and is included in the factory Works’ quality
manual. The manufacturer has full responsibility for the quality of the cement released from the depot. In
a dispatching centre, in contrast, the facility is not at all linked to the factory and it is an intermediary (an
entity taking certified cement, acting independently and operating bet

Introduction to this Guidelines Document
Purpose
The purpose of this Guidelines Document is to provide explanatory detail on points not fully elaborated in
EN 197-2. It is intended for use by manufacturers and by product certification bodies involved in the
certification of cement following EN 197-2, in particular for the issuing of an EC certificate of constancy of
performance.
This document does not deal with the necessary internal procedures that the product certification bodies will
have.
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 may 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, that is
expected from the application of EN 197-2 together with these Guidelines.
This Guidelines Document is based on existing situations for production, evaluation of conformity and
certification of cements. It may happen that product certification bodies be confronted by a situation different
to those included in this document. In such a case, specific procedures should be elaborated on a case by
case situation and be approved and fully recorded by the product certification body. These specific procedures
should always fulfil the requirements of EN 197-1 and EN 197-2 and lead to the same level of confidence in
product conformity that would be achieved by application of this Guidelines 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.

1 Scope
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.
1)
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.
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 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.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
AVCP
abbreviation for assessment and verification of constancy of performance
3.2
certificate of constancy of performance of the product
document issued under the rules of the scheme for the AVCP indicating that adequate confidence is provided
that cement is in conformity with the relevant product specification standard
Guidance
The term “certificate of constancy of performance of the product” refers to certificates of constancy of
performance of the product issued by a product certification body under the rules of EN 197-2. This
includes an EC certificate of constancy of performance of the product issued in relation to the CPR.
3.3

protected mark applied on the basis of the certificate of constancy of performance of the product (see 3.2)
Guidance
The term “protected mark” includes registered mark, regulated mark and CE marking.
3.4
certified cement
cement for which a certificate of constancy of performance of the product (see 3.2) has been issued
3.5
initial period
immediate period starting after the first issuing of the certificate of constancy of performance of the product for
a cement and at the latest from the first dispatching of cement
3.6
product certification body
impartial body, governmental or non-governmental, possessing the necessary competence and responsibility
to carry out AVCP according to given rules of procedure and management
3.7
factory production control
documented, permanent and internal control of production in a factory, in accordance with the relevant
harmonized technical specifications
3.8
factory
facility used by a manufacturer for the production of cement using equipment which is suitable for continuous
mass production of cement including, in particular, equipment for adequate grinding and homogenization and
the necessary silo capacity for the storage and dispatch of each cement produced
Note 1 to entry: This equipment and the production control applied allow the control of production with sufficient
accuracy to ensure that the requirements of the relevant product specification standard are met.
Guidance
According to EN 197-1, Clause 4, common cements (CEM cements) consist of different materials and are
statistically homogeneous in composition resulting from quality assured production and material handling

kSIST-TP FprCEN/TR 14245:2014
FprCEN/TR 14245:2014 (E)
processes. A high degree of uniformity in all cement properties is obtained through continuous mass
production processes, in particular, adequate grinding and homogenization processes. Similar
considerations apply for other cements.
Three categories of “factory” are recognized:
traditional full cement factories, where clinker and cement are produced on the same site;
grinding plants, where cement is produced by grinding supplied cement constituents;
blending plants, where ground cement constituents, which may be received already combined as
cement, are blended to produce finished cement.
The following operating steps, which apply for all of these types of factory, are essential in the
manufacturing process. These steps are needed to ensure the necessary uniformity, continuity and
suitability of the cement properties as well as the ability to meet the other requirements of the relevant
product specification standard:
use of separate and adequate storage for the cement constituents;
Controlling the cement constituents – including, where relevant, their fineness and particle size
distribution, and therefore their grinding – to achieve a performance of the cement compatible with
the requirements of the product specification standard;
proportioning the cement constituents in order to achieve the target composition of the cement;
homogenization of the cement constituents by grinding, or by mixing where relevant;
storage of finished product, in silos of adequate capacity, allowing proper identification of mass
quantities of product and giving the possibility of taking spot samples at any time without prior notice.
Factories can only be operated by manufacturers which have personnel with sufficient experience and
knowledge in all operating steps important for cement quality and which have the people, test procedures
and test equipment to test, evaluate and correct the cement being produced. The definition of factory in
EN 197-2 takes it, therefore, for granted that all operating steps listed above are carried out in effect under
the same quality responsibility.
3.9
new factory
factory which is not already producing cement(s) certified using this European Standard
3.10
existing factory
factory which is already producing cement(s) certified using this European Standard
3.11
depot
bulk cement handling facility (not located at the factory) used for the dispatch of cement (whether in bulk or
bagged) after transfer or storage where the manufacturer has full responsibility for all aspects of the quality of
the cement
Guidance
It is important to point out the difference between a depot and a dispatching centre. The difference consists
essentially of the linkage to the factory and the responsibility for the quality of the cement. In the case of a
depot the facility is strictly linked to the factory and is included in the factory Works’ quality manual. The
manufacturer has full responsibility for the quality of the cement released from the depot. In a dispatching

FprCEN/TR 14245:2014 (E)
centre, in contrast, the facility is not at all linked to the factory and it is an intermediary (an entity taking
certified cement, acting independently and operating between the manufacturer and a subsequent
customer) who has full responsibility for the quality of the cement dispatched. A dispatching centre, being
independent from the factory cannot be included in a Works’ quality manual, but it has to ensure, using
appropriate rules, that the quality of an already certified cement does not undergo any cha
