This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 193.
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.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye 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 13872:2026) has been prepared by Technical Committee CEN/TC 193 “Adhesives”,
the secretariat of which is held by UNE.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 13872:2004.
— term “hydraulic setting floor smoothing and/or levelling compounds” changed to “cementitious and
calciumsulfate-based floor levelling compounds”;
— concretisation of the scope;
— editorial changes.
Introduction
Persons using this document are to be familiar with normal laboratory practice.
This document does not purport to address all the safety problems, if any, associated with its use.
It is the responsibility of the user to establish health and safety practices and to ensure compliance with
any European and national regulatory conditions.
1 Scope
This document specifies the measurement of dimensional change of set cementitious and calcium sulfate-
based floor levelling compounds after mixing with a liquid, e.g. water.
This document applies to cementitious and calcium sulfate-based floor levelling compounds used for the
preparation of subfloors to ensure the suitability of the substrate prior to the installation of floor
coverings. By using the floor levelling compound, a homogeneous layer is built up on the load-bearing
substrate, to ensure consistent absorbency, evenness and strength.
