This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 51.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania,
Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

European foreword
This document (prEN 197-1:2018) has been prepared by Technical Committee CEN/TC 51 “Cement and
building lime”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 197-1:2011.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports basic requirements of Regulation
(EU) No 305/2011 amended by the Commission Delegated Regulations (EU) No 157/2014 of
30 October 2013, No 568/2014 of 18 February 2014 and No 574/2014 of 21 February 2014.
For relationship with Regulation (EU) No 305/2011, see informative Annex ZA, which is an integral part
of this document.
Annexes A and ZA are informative.
Compared to the version EN 197-1:2011 the following major changes have been included in this
document:
— CEM II/C and CEM VI have been defined as new cement types;
— CEM V has been renamed as Slag-pozzolanic cement;
— the total alkali content was included as part of the essentials characteristics and corresponding
rules were laid down;
— Annex ZA has been revised.
EN 197, Cement, is currently composed with the following parts:
— Part 1: Composition, specifications and conformity criteria for common cements
— Part 2: Conformity evaluation
The preparation of a standard for cement was initiated by the European Economic Community (EEC) in
1969 and, at the request of a member state later in 1973, the work was given to the European
Committee for Standardization (CEN). The Technical Committee CEN/TC 51 was entrusted with the
task of preparing a cement standard for the countries of Western Europe, comprising the EEC and EFTA
members.
In the early eighties, CEN/TC 51 decided to include in the standard for cement only those cements
which are intended for use in any plain and reinforced concrete and which are familiar in most
countries in Western Europe because they have been produced and used in these countries for many
years. The EU Construction Products Directive (89/106/EEC) required the incorporation of all
traditional and well-tried cements in order to remove technical barriers to trade in the construction
field. There are currently no criteria for the descriptions “traditional” and “well tried” and it was
maintained the need to separate the “common cements” from “special cements”, i.e. those with
additional or special properties.
The requirements in this standard are based on the results of tests on cement in accordance with
EN 196-1, EN 196-2, EN 196-3, EN 196-5, EN 196-6, EN 196-7, EN 196-8, and EN 196-9. The scheme for
the assessment and verification of constancy of performance (AVCP) of common cements including
common cements with low heat of hydration and common cements generally accepted as being sulfate
resisting and of special cements are specified in EN 197-2.
In 2006, CEN/TC 51 began to investigate the possible standardization of some new cements produced
using traditional constituents and manufacturin
