General Information
Overview
CEN/TR 16912:2016 - "Guidelines for a procedure to support the European standardization of cements" - is a CEN Technical Report prepared by CEN/TC 51. It provides guidance on the process and dossier requirements to support European standardization of new cements (and similar products) not covered by existing European standards. The document describes classification of new cements, criteria to demonstrate fitness for intended use, steps for application and evaluation, and issues such as testing, durability, environmental and health aspects, and intellectual property.
Key topics and requirements
- Classification of new cements: Three categories determine the assessment scope:
- Category 1 - new combinations of traditional, well-tried constituents.
- Category 2 - essentially existing cement types but containing one or more new constituents.
- Category 3 - cements substantially different from existing standards (e.g., new clinker types or novel chemistry).
- Dossier contents required for a New Work Item (NWI) proposal:
- Product definition and intended use (including assumed working life).
- Proposed categorization and constituents (with characterization criteria for new constituents).
- Manufacturing process, packaging, transport and storage.
- Proposed testing methods, testing laboratories (competence criteria) and test results.
- Proposal for Assessment and Verification of Constancy of Performance (AVCP) system and conformity criteria.
- Information on patents and other IPR relevant to standardization.
- Assessment of fitness for use: Demonstrate mechanical, physical, chemical and durability-related characteristics appropriate to the intended use. For Category 2 and 3 cements, additional evaluation of environmental and health impacts and, for Category 3, relevant practical experience (e.g., via ETA) is required.
- Testing and laboratories: Testing should be performed by competent laboratories, preferably accredited to EN ISO/IEC 17025 or otherwise approved by CEN/TC 51. Test methods and conditions should be agreed where possible beforehand.
- Evaluation process: CEN/TC 51 evaluates dossiers case-by-case, may consult working groups or other committees, and is responsible for the decision to begin standardization.
Applications and users
- Cement manufacturers and R&D teams developing low-clinker or innovative binders.
- National standardization bodies and CEN technical committees preparing NWIs.
- Testing laboratories and conformity assessment bodies involved in AVCP.
- Specifiers, concrete producers, precast manufacturers and construction clients assessing new cement fitness for structural use.

Introduction
The willingness to improve construction products leads to the optimization of existing cements as well
as to the development of new binders. Improvement may concern in particular the performance of the
products, the reduction of production costs or the lowering of the environmental impact. With regards
to the environment, a fundamental policy objective of the European Union is to encourage/incentivise a
reduction in CO emissions within a framework of sustainable development. Cement manufacturers are
reducing their specific CO emissions e.g. by the production of cements with a lower clinker content. At
the same time, the expectations of contractors, ready-mixed concrete producers and precast concrete
manufacturers should also be met by maintaining high levels of performance in cements and in the
durability of concrete.
Existing cement standards, in particular EN 197-1, allow manufacturers to select cement compositions
with low clinker content, i.e. CEM III/B and C, CEM IV/B, CEM V. However, these cements are often used
for their good resistance to chemically aggressive environments but do not necessarily achieve, in
concrete, the early age strength required where formwork is to be removed at less than 24 h.
Maintaining performance, in particular early strength and durability related characteristics, while
reducing specific CO emissions by the development of new types of cement is expected to be one of the
main challenges of the coming years.
When considering such new cements intended to be used to produce structural concrete the question
arises whether these products should be covered by European Standards or by European Technical
Assessments (ETAs). For an answer, the various EU policy documents referenced in the bibliography
should be considered, in particular the “Council Conclusions on standardization and innovation
(Brussels, 25 September 2008)” [7] which highlight “the essential contribution which standardization
can make towards developing innovation and competitiveness, by facilitating access to markets,
enabling interoperability between new and existing products, services and processes, enhancing
protection of users, giving consumers confidence in innovations and disseminating research results”.
CEN and CENELEC have responded to all the EU initiatives and adopted, in October 2008, an integrated
approach titled “Standardization Innovation and Research (STAIR)”. From this common approach of the
EU and CEN, it is clear that European standardization may cover innovation.
An application to standardize a new cement should be submitted to the Technical Committee
CEN/TC 51 based on a dossier introduced by the applicant who may, according to CEN/CENELEC
Internal Regulations – Part 2:2015 [14], be a national standardization body (CEN Member), a CEN
Technical Committee, the EU or EFTA Secretariat, an international organization or an European trade,
professional, technical or scientific organization. It is essential that all applicants are aware in advance
of the information they should provide to CEN/TC 51 in the dossier in order to demonstrate the fitness
for intended use of the new cement. For this purpose, CEN/TC 51 has prepared this CEN Technical
Report.
1 Scope
This CEN Technical Report provides guidance for the procedure to be followed in order to support the
European standardization of new cements that are not covered by an existing European Standard.
The term “new cement” has been used in this document to describe its primary focus; however, this
same guideline procedure may be used for other products to be standardized by CEN/TC 51.

4 Procedure of application and standardization of a new cement
4.1 General information on standardization processes
For general information on the process of European product standardization, see
http://boss.cen.eu/Pages/default.aspx.
4.2 Classification of new cements
The procedure to be followed in order to support the European standardization of a new cement
depends on the type of the cement, i.e. on the question whether the new cement is similar to cements
that already have been standardized by CEN/TC 51. Following this principle, new cements can be
classified in the following three categories:
1) Category 1: cement from a new combination of traditional and well-tried constituents;
2) Category 2: cement basically corresponding to cement types defined in existing standards but
containing one or more new constituents;
3) Category 3: cement differing substantially from those types defined in existing standards, e.g.
produced with a new kind of clinker or based on different physicochemical phases/principles.
Cement of category 2 should be similar to common cements, i.e. its hydration should be based on the
formation of calcium silicate hydrates (CSH).
4.3 General criteria for the assessment of new cements
The general requirements for assessing new cements differ depending on their classification according
to 4.2; these requirements should be fulfilled before CEN/TC 51 considers the possibility of European
standardization of a new cement:
— for cements of category 1, the mechanical, physical and chemical performances listed in 5.3 as well
as durability related characteristics described in 5.4.3 should be assessed, taking into account the
intended use of the cement.
— for cements of category 2, in addition to the requirements for cement of category 1, the potential
environmental and health impacts of end-use construction products that incorporate the cement
should be assessed as described in 5.4.4 and 5.4.5, respectively.
— for cements of category 3, in addition to the requirements for cement of category 2, also relevant
practical experience should be gained under conditions approved by CEN/TC 51, e.g. through an
ETA or another comparable procedure, for assessing the fitness for the intended use prior to
identifying the general criteria, amongst other things, for the possibility of European
standardization.
The categorization of new cements and the corresponding requirements are summarized in Table 1.

4.4 Application for the standardization of a new cement
4.4.1 General
An application for the standardization of a new cement should be presented to CEN/TC 51 for approval
using, as the basis of, the CEN form for a New Work Item (NWI) proposal (see
http://boss.cen.eu/Pages/default.aspx) and a dossier (4.4.2). The dossier may be submitted with the
application where considered by the applicant to be complete, alternatively initial proposals for testing
procedures etc. may accompany the application (see 4.4.2).
4.4.2 The dossier and its contents
The dossier should provide the necessary information, especially to demonstrate the fitness for
intended use of the new cement, i.e. in particular the following:
— definition and, where applicable, name and/or brand name of the product;
— intended use of the product including assumed working life of construction products made using
the product;
— specific terms used for the product;
— information on patents and other intellectual property rights (IPR) that may be relevant for the
standardization of the new cement;
— proposal concerning the categorization of the new cement according to 4.2;
— constituents of the product, for new constituents appropriate criteria for their characterization;
— description of the manufacturing process;
— packaging, transport and storage of the product;
— methods for the identification and testing of the product and its constituents, i.e. applicable testing
standards and/or other test methods including equipment necessary for the testing laboratories;
— name and qualifying criteria for the competence of laboratories assigned to carry out the tests;
— results of tests carried out;
— proposal concerning the system for assessment and verification of constancy of performance (AVCP
system) and the conformity criteria for the new cement.
The applicant is free to introduce – as a first step – the description of the product together with a
proposal for the testing procedures (including all relevant testing conditions, see provisions given in
5.4) and for the laboratories (including qualification) designated to be assigned with the tests. This is
recommended in particular for the testing of durability related characteristics. After approval of the
proposal, the risk is lower that testing results are not accepted afterwards by CEN/TC 51.
Testing should be undertaken by competent laboratories. As a rule, the laboratories involved in the
testing procedures should be accredited according to EN ISO/IEC 17025 for all testing methods to be
used. If this is not or not completely possible, it is strongly recommended that the laboratories involved
in the testing are approved by CEN/TC 51 on the basis of the information on the competence of the
laboratory to be supplied by the applicant before undertaking the testing.
4.5 Evaluation and decision by CEN/TC 51
The evaluation of an application, and the dossier submitted by the applicant, and any decision to begin
the standardization process for a new cement, are in the sole responsibility of CEN/TC 51.
The discussion and evaluation of the dossier will always be on a case-by-case basis. In this regard,
distinction should be made between cements for normal structural application in construction and
cements designed and produced intentionally for a specific use.
CEN/TC 51 may task one or more of its Working Groups and/or ask other CEN Technical Committees to
contribute to the discussion and to the evaluation process.
The following aspects will be considered by CEN/TC 51 during the evaluation process:
— classification of the new cement according to 4.2 and its intended use;
— characteristics of the new cement which are relevant to its fitness for use;
— methods for the verification and assessment of the relevant product characteristics, i.e. test
procedures proposed in the dossier to demonstrate the fitness for the intended use of the new
cement;
— qualification of the testing laboratory/laboratories;
— test results;
— AVCP system and associated rules for the assessment and verification of constancy of performance
of the new cement proposed in the dossier.
5 Assessment of fitness for use
5.1 Meaning of “fitness for use”
“Fitness for (the intended) use” of a construction product means that the product has such
characteristics that the works in which it is to be incorporated can, if properly designed and built,
— satisfy the basic requirements for construction works when and where such works are subject to
regulations containing such requirements and
— be fit for their intended use, account being taken of economy and in this connection satisfy the basic
requirements for construction works for an economically reasonable working life, if normally
maintained.
Therefore, it is necessary that the intended use of the new cement be clearly defined in the dossier.
5.2 Elements of the assessment of fitness for use
The assessment of the fitness of a new cement for its intended use should include the following:
— the identification of the characteristics of the new cement which are relevant to its fitness for use;
— the establishment of methods for the verification and assessment of the relevant product
characteristics and the expression of the respective product performances;
— the demonstration of practical experiences for cement of category 3.
5.3 Characteristics of the new cement which are relevant to its fitness for use
The product characteristics given in Table 2 may be relevant to the fitness for use of the new cement.
It should be stated and explained in detail in the dossier which of the characteristics are relevant and
which are not, taking into account the intended use and the classification of the cement in a category
according to 4.2. If other product characteristics not listed in Table 2 are relevant to the fitness for use
of the new cement, this should in addition be stated and explained in the dossier.
