Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 219, Floor coverings.
This second edition cancels and replaces the first edition (ISO 23999:2008), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— cross-references within the document have been updated;
— minor editorial changes have been made;
— the scope has been broadened to allow testing of planks;
— the possibility of additional testing temperatures has been introduced;
— the specimen dimensions have been specified;
— an appendix has been added to allow for dimensional changes immediately after exposure to
specified heated exposure conditions.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.

Resilient floor coverings — Determination of dimensional
stability and curling after exposure to heat
1 Scope
This document specifies a method for determining dimensional stability and curling of resilient floor
coverings, in the form of sheets, tile or planks after exposure to heat.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https: //www .iso .org/obp
— IEC Electropedia: available at http: //www .electropedia .org/
3.1
dimensional stability
ability of a resilient floor covering to retain its original dimensions after exposure to heat, under
specified conditions
3.2
curling
vertical deformation appearing on the specimen after exposure to a heat treatment, under specified
conditions
3.3
domed material
area of specimen that does not lie flat against support plate when centred
4 Principle
4.1 Dimensional stability
The relative change in distance between marks or a specific location on a test specimen is measured
before and after exposure to a heat treatment, under specified conditions. In the case of tiles and planks,
measurements may be made using a block and dial gauge assembly and marking of the test sp
