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
certification bodies involved in the certification of cement following EN 197-2, in
particular for the issuing of an EC Certificate of Conformity.
This Document does not deal with the necessary internal procedures that the
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 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 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 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 Standard is reproduced in full and is followed by guidance, which is provided
only for those clauses where clarification or elaboration is needed.

Foreword
This European Standard has been prepared by Technical Committee CEN/TC 51
"Cement and building limes", the secretariat of which is held by IBN.
This European Standard supersedes ENV 197-2:1995.
Annex A of EN 197-2 is normative, annex B is informative.
According to the CEN/CENELEC Internal Regulations, the national standards
organisations of the following countries are bound to implement this European
Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany,
Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain,
Swede, Switzerland and the United Kingdom.
1 Scope
EN 197-2 specifies the scheme for the evaluation of conformity of cements to their
corresponding product specification standards, including certification of conformity by
a 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
certification body. It also provides rules for actions to be followed in the event of non-
conformity, the procedure for the certification of conformity and requirements for
dispatching centres.
In EN 197-2 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 EN 197-2 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.
„
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 Directive. The products for which EN 197-2 is applicable
are: the 27 common cement products, refer EN 197-1, and masonry cements,
refer prEN 413-1. It will also be applicable for low heat cements, sulfate resisting
cements and calcium aluminate cements when the corresponding product
specification standards are adopted.
“ 2 Normative references

publications. These normative references are cited at the appropriate places in the
text and the publications are listed hereafter. For dated references, subsequent
amendments to or revisions of any of these publications apply to EN 197-2 only when

3 Definitions
For the purposes of EN 197-2, the following definitions apply:
3.1 Specific definitions
3.1.1
certificate of conformity
document issued under the rules of this scheme for the evaluation of conformity
indicating that adequate confidence is provided that cement is in conformity with the
relevant product specification standard „
Guidance
The term “certificate of conformity” refers to certificates of conformity issued by a
certification body under the rules of EN 197-2. This includes an EC Certificate of
Conformity issued in relation to the CPD.
“ 3.1.2
conformity mark
protected mark applied on the basis of the certificate of conformity (see 3.1.1) „
Guidance
The term “protected mark” includes registered mark, regulated mark and CE
marking.
“ 3.1.3
certified cement
cement for which a certificate of conformity (see 3.1.1) has been issued
3.1.4
initial period
immediate period after the first issuing of the certificate of conformity for a cement
3.1.5
certification body
impartial body, governmental or non-governmental, possessing the necessary
competence and responsibility to carry out conformity certification according to given
rules of procedure and management
3.1.6
factory production control
permanent internal control of cement production exercised by the manufacturer
consisting of internal quality control complemented by autocontrol testing
3.1.7
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. 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 clause 4 of 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 properties is obtained through continuous mass
production processes, in particular, adequate grinding and homogenisation
processes. Similar considerations apply for other cements.
Three categories of “factory” are recognised:
- 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;
- Homogenisation 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 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.
“ 3.1.8
new factory
factory which is not already producing cement(s) certified under this scheme
3.1.9
existing factory
factory which is already producing cement(s) certified under this scheme
3.1.10
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 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 change.
Depots are included in the Works’ quality manual. 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.
“ 3.1.11
dispatching centre
bulk cement handling facility (not located at the factory) used for the dispatch of
cement after transfer or storage where an intermediary has full responsibility for all
aspects of the quality of the cement „
Guidance
See guidance under 3.1.10 and 9.1.
“ 3.1.12
intermediary
natural or legal person who takes from the manufacturer bulk cement certified
according to EN 197-2 and bearing the conformity mark, who undertakes full
responsibility for maintaining in a bulk handling facility all aspects of the quality of the
cement and who supplies the cement onwards to a further person
3.1.13
confirmation autocontrol testing
continual testing carried out by an intermediary which consists of testing of samples
taken by the intermediary at the point(s) of release from the dispatching centre
