European foreword
This document (prEN 197-10:2025) has been prepared by Technical Committee CEN/TC 51 “Cement and
building limes”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.
Introduction
The purpose of this document is to provide a scheme for the evaluation of compliance with the
requirements in Regulation (EC) No 1907/2006.
Regulation (EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006
concerning the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH),
establishing a European Chemicals Agency, amending Directive 1999/45/EC and repealing Council
Regulation (EEC) No 793/93 and Commission Regulation (EC) No 1488/94 as well as Council Directive
76/769/EEC and Commission Directives 91/155/EEC, 93/67/EEC, 93/105/EC and 2000/21/EC contain
prohibitions, among other requirements, against placing on the market or using cement and cement-
containing mixtures if they contain, when hydrated, more than 2 mg/kg (0,0002 %) soluble
chromium (VI) of the total dry weight of the cement. This legislation is intended to minimize the
occurrence of chromate-related allergic contact dermatitis arising from the use of cement or cement-
containing preparations. In order to comply with the regulatory limit, in most cases a reducing agent is
added during production of the cement or cement-containing preparation, which converts soluble
hexavalent chromium into insoluble trivalent chromium during hydration. Regulation (EC) No
1907/2006 prescribes that information on the packing date, as well as on the storage conditions and the
storage period appropriate to maintaining the activity of the reducing agent and to keeping the content
of soluble chromium VI below the limit is legibly indicated on packaging and dispatch documentation.
1 Scope
This document specifies the scheme for the assessment of conformity with the regulatory limit for water-
soluble hexavalent chromium.
This document provides technical rules for factory production control, including autocontrol testing of
samples, and for assessment of factory production control. It also provides rules for actions to be followed
in the event of non-compliance with the procedure set in place, or that of exceeding the limit of water-
soluble hexavalent chromium, hereafter to be referred to as “water-soluble chromium (VI)”.
This document applies to all cements within the meaning of the term “cement”.

Methods of testing cement - Part 12: Reactivity of cement constituents - Heat of hydration and bound water content methods
SIST EN 196-12:2025

This document specifies two equivalent test methods to assess the chemical reactivity of a pozzolanic or latent hydraulic cement constituent or concrete addition by measurements of heat of hydration (see Clause 5 and 8.3 Method A, Heat of Hydration) or bound water content (see Clause 5 and 8.4 Method B, Bound Water Content) of hydrated pastes composed of the cement constituent or concrete addition, calcium hydroxide, calcium carbonate, potassium sulfate, and potassium hydroxide cured at 40 °C for 72 h and 168 h (3 days and 7 days).
These two test methods measure chemical reactivity of test specimens intended for use as cementitious materials, such as cement constituents and concrete additions. The test methods do not distinguish between latent hydraulic and pozzolanic reactivity.
The test methods are used for qualification purposes if the cement constituents or concrete additions are tested at the fineness as specified by the respective product standards. In the absence of a product standard or a specification in the product standard, the constituents are tested at the fineness of the intended use.
NOTE   In case the test methods are used for purposes of comparison of intrinsic reactivity, cement constituents are tested at similar fineness, where possible.
The test methods are also used for testing other new constituents that are latent hydraulic or pozzolanic and that are not covered by EN 197 series product standards. However, for such new constituents the validity of the underlying correlations with strength development have not been verified; in consequence the test results can only be used for informative and indicative purposes.
Furthermore, these test methods are used in manufacturing control of cement constituents for assessing their latent hydraulic or pozzolanic reactivity.

Cement - Guidelines for the application of EN 197-2: Assessment and verification of constancy of performance
SIST-TP CEN/TR 14245:2020

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.

Method for the determination of C3A in the clinker from cement analysis
SIST-TP CEN/TR 17365:2019

This document describes the analytical procedures used to determine the content of C3A in the clinker starting from a chemical analysis on cement. The method can be applied to CEM type I and IV for the determination of the requirement of C3A, as defined on EN 197 1.
This document describes two methods, traditional wet and XRF analysis (EN 196 2), which can be considered to be equivalent, in the scope of this CEN/TR 17365, for the determination of Al2O3, Fe2O3 and SO3.
The same methods are described in EN 196 2, but for the scope of this document, the X-ray fluorescence (XRF) is the preferred method to be used for the determination of Al2O3, Fe2O3 and SO3.

SIST EN 196-11:2019

This document specifies the apparatus and procedure for determining the heat of hydration of cements and other hydraulic binders at different test ages by isothermal conduction calorimetry.
This test procedure is intended for measuring the heat of hydration of cement up to 7 days in order to obtain correspondence between Isothermal Conduction Calorimetry (ICC) and EN 196 8 and EN 196 9. Nevertheless this test duration may be critical for some apparatus, even if they can work properly at shorter test ages.
Contrary to EN 196 8 this method gives the heat of hydration continuously over the time. Additionally, the heat flow versus time is given.
