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.

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.

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.

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.

sufficient accuracy.
---------------------- Page: 9 ----------------------
SIST-TP CEN/TR 14245:2020
CEN/TR 14245:2020 (E)
Guidance

According to EN 197-1, 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 characteristics 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.

or bagged, after transfer or storage where the manufacturer has full responsibility for all aspects of the

quality of the cement
Guidance

In the case of a depot the facility is strictly linked to the factory and is included in the factory

Works’ quality documentation. The manufacturer has full responsibility for the quality of the

cement released from the depot. Depots are included in the Works’ quality documentation. An

entity other than the manufacturer may own and operate the depot but it does this on behalf of and

under the strict quality management responsibility of the manufacturer.

CEN/TR 14245:2020 (E)
4 Factory production control
4.1 General requirements
4.1.1 Concept

Factory production control means the permanent internal control of cement production and consists of

internal quality control (see 4.2) complemented by autocontrol testing of samples of cement taken at

the point of release (see 4.3).

NOTE 1 The requirements of this document as regards factory production control apply to factories and their

depots.

NOTE 2 The requirements of this document in regards to factory production control take into account the

clauses of EN ISO 9001 [1] which are relevant to the production, process control and testing of cement.

Guidance

The purpose of factory production control is to ensure that the cement is manufactured in a

controlled way to meet all of the requirements of the relevant product specification standard. In

order for a product certification body to verify such a system, it has to be documented in a

structured way. This is carried out in a Works’ quality documentation, supported and cross-

referenced by a series of procedures, work instructions and other associated and relevant

documents. These need to be clear, concise and adopt recommended good practices where

applicable. The factory production control system may form part of a wider, integrated

management system provided it can be demonstrated that all applicable EN 197-2 requirements

are addressed. See also Clause 4.1.2 of the document.
4.1.2 Works' quality documentation

The manufacturer's documentation and procedures for factory production control shall be described in

a Works' quality documentation, which shall adequately describe, amongst other things, for each

factory and depot:

a) the quality aims and the organizational structure, responsibilities and powers of the management

with regard to product quality and the means to monitor the achievement of the required product

quality and the effective operation of the internal quality control (see 4.1.3 and 4.2);

b) the manufacturing and quality control techniques, processes and systematic actions that will be

used (see 4.2.1, 4.2.3 and 4.3.2);

c) the inspections and tests that will be carried out before, during and after manufacture, and the

frequency with which they will be carried out (see 4.2.2, 4.3.1 and 4.3.3).

The Works' quality documentation shall address and document the procedures operated to ensure that

the manufactured cement conforms to the performance(s) declared in accordance with the relevant

product standard. The documentation may reference associated documents which provide further

details of the autocontrol testing of samples and the internal quality control. For the purpose of this

scheme, the term Works' quality documentation shall be considered to include these associated

documents.

1 This testing corresponds also to the “further testing of samples taken at the manufacturing plant” mentioned in

Delegated Regulation (EU) No 568/2014 amending Annex V to Regulation (EU) No 305/2011 (Construction Products

Regulation) .
[4]
---------------------- Page: 12 ----------------------
SIST-TP CEN/TR 14245:2020
CEN/TR 14245:2020 (E)

In the case of an existing quality management system according to EN ISO 9001, the corresponding

quality documentation may also be applied for product certification if it meets all the requirements of

this document which are relevant to the factory production control of cement.
Guidance
Illustrative example of responsibilities – For information only
The producer has three overall responsibilities:

— To have an approach for production control and testing (to ensure that adequate quality

procedures exist);
— To ensure that the procedures are carried out;
— To ensure that the approach and application are giving the expected results.

Responsibility and authority for personal responsible for the quality of the product and FPC

system should be clear, communicated and understood within the organization.
Examples of responsibilities that should be defined are:

— The co-ordination, monitoring and updating of the Works’ quality documentation procedures;

— Ensuring all personnel at every level is kept informed of working methods, procedures,

specifications and quality targets;

— Setting the requirements for process control and supervising their written transmission to the

appropriate personnel;

— The system of management of corrective actions for the entire scope of the FPC system;

— Assessing the conformity of raw materials to the relevant specifications;
— Controlling of off-specification constituents and non-conforming cements;
— The identification and resolution of non-conformities in the FPC system;

— Supervising the recording and processing of relevant data and consequent approval;

— Provide the organization with periodic reports on the compliance status of the cement.

There needs to be a quality plan for the production of conforming cement and whilst it shall be

recognized that the plan can take on one of many forms and include such things as process flow

charts and control tables, it shall show how each of the parts of the process are connected. There

shall be a clear indication of where samples are taken and at what frequency, together with the

tests to be applied. Targets and acceptability criteria should also be documented.

In the case of an existing quality management system in accordance with EN ISO 9001, it should be

clearly stated in the Works’ quality documentation that the system is also used for factory

production control according to EN 197-2 and the relevant product specification standard.

4.1.3 Quality management system
4.1.3.1 Quality policy statement

The Works' quality documentation shall include a statement by management defining its quality policy,

objectives and commitments to the attainment of product quality.
Guidance

The quality policy statement is a document signed normally by the managing director of the

company or by the manager of the factory, depending on the organization of the company, or by

both. It should include the quality aims and its commitment to meeting the requirements of

standards and/or of its customers and to ongoing improvement, both internally and externally. It

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.

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 [1] should be used 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.

Note 1 to entry: This equipment and the production control applied allow the control of production with

sufficient accuracy.
---------------------- Page: 10 ----------------------
kSIST-TP FprCEN/TR 14245:2019
FprCEN/TR 14245:2019 (E)
Guidance

According to EN 197-1, 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 characteristics 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.

new factory
factory which is not already producing cement(s) certified using EN 197-2
3.7
existing factory
factory which is already producing cement(s) certified using EN 197-2

3.8
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

In the case of a depot the facility is strictly linked to the factory and is included in the factory

Works’ quality documentation. The manufacturer has full responsibility for the quality of the

cement released from the depot. Depots are included in the Works’ quality documentation. An

entity other than the manufacturer may own and operate the depot but it does this on behalf of and

under the strict quality management responsibility of the manufacturer.

4 Factory production control
4.1 General requirements
4.1.1 Concept

Factory production control means the permanent internal control of cement production and consists of

internal quality control (see 4.2) complemented by autocontrol testing of samples of cement taken at

the point of release (see 4.3).

NOTE 1 The requirements of this document as regards factory production control apply to factories and their

depots.

NOTE 2 The requirements of this document in regards to factory production control take into account the

clauses of EN ISO 9001 [2] which are relevant to the production, process control and testing of cement.

Guidance

The purpose of factory production control is to ensure that the cement is manufactured in a

controlled way to meet all of the requirements of the relevant product specification standard. In

order for a product certification body to verify such a system, it has to be documented in a

structured way. This is carried out in a Works’ quality documentation, supported and cross-

referenced by a series of procedures, work instructions and other associated and relevant

documents. These need to be clear, concise and adopt recommended good practices where

applicable. The factory production control system may form part of a wider, integrated

management system provided it can be demonstrated that all applicable EN 197-2 requirements

are addressed. See also Clause 4.1.2 of the document.
4.1.2 Works' quality documentation

The manufacturer's documentation and procedures for factory production control shall be described in

a Works' quality documentation, which shall adequately describe, amongst other things, for each

factory and depot:

a) the quality aims and the organizational structure, responsibilities and powers of the management

with regard to product quality and the means to monitor the achievement of the required product

quality and the effective operation of the internal quality control (see 4.1.3 and 4.2);

b) the manufacturing and quality control techniques, processes and systematic actions that will be

used (see 4.2.1, 4.2.3 and 4.3.2);

c) the inspections and tests that will be carried out before, during and after manufacture, and the

frequency with which they will be carried out (see 4.2.2, 4.3.1 and 4.3.3).

The Works' quality documentation shall address and document the procedures operated to ensure that

the manufactured cement conforms to the performance(s) declared in accordance with the relevant

product standard. The documentation may reference associated documents which provide further

details of the autocontrol testing of samples and the internal quality control. For the purpose of this

scheme, the term Works' quality documentation shall be considered to include these associated

documents.

1 This testing corresponds also to the “further testing of samples taken at the manufacturing plant” mentioned in

Delegated Regulation (EU) No 568/2014 amending Annex V to Regulation (EU) No 305/2011 (Construction Products

Regulation).
---------------------- Page: 13 ----------------------
kSIST-TP FprCEN/TR 14245:2019
FprCEN/TR 14245:2019 (E)

In the case of an existing quality management system according to EN ISO 9001, the corresponding

quality documentation may also be applied for product certification if it meets all the requirements of

this document which are relevant to the factory production control of cement.
Guidance
Illustrative example of responsibilities – For information only
The producer has three overall responsibilities:

— To have an approach for production control and testing (to ensure that adequate quality

procedures exist);
— To ensure that the procedures are carried out;
— To ensure that the approach and application are giving the expected results.

Responsibility and authority for personal responsible for the quality of the product and FPC

system should be clear, communicated and understood within the organization.
Examples of responsibilities that should be defined are:

— The co-ordination, monitoring and updating of the Works’ quality documentation procedures;

— Ensuring all personnel at every level is kept informed of working methods, procedures,

specifications and quality targets;

— Setting the requirements for process control and supervising their written transmission to the

appropriate personnel;

— The system of management of corrective actions for the entire scope of the FPC system;

— Assessing the conformity of raw materials to the relevant specifications;
— Controlling of off-specification constituents and non-conforming cements;
— The identification and resolution of non-conformities in the FPC system;

— Supervising the recording and processing of relevant data and consequent approval;

— Provide the organization with periodic reports on the compliance status of the cement.

There needs to be a quality plan for the production of conforming cement and whilst it shall be

recognized that the plan can take on one of many forms and include such things as process flow charts

and control tables, it shall show how each of the parts of the process are connected. There shall be a

clear indication of where samples a
