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 of 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

This document was prepared by Technical Committee ISO/TC 219, Floor coverings, in collaboration with
the European Committee for Standardization (CEN) Technical Committee CEN/TC 134, Resilient, textile
and laminate floor coverings, in accordance with the Agreement on technical cooperation between ISO
and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 23999:2018), which has been technically
revised.
The main changes are as follows:
— cross-references within the document have been updated;
— update to the dimensional stability and curling calculation sections of the method;
— update of Annex A with more detailed calculation.
Any feedback or questions on this document should be directed to the user’s national standards body. A

INTERNATIONAL STANDARD ISO 23999:2021(E)
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, tiles 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 terminology 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.
4.2 Curling
The vertical deformations are measured in the test specimen after the specified heat treatment.
Test specimens are placed in an oven at an elevated temperature, after which curling and dimensional
stability are determined. In the case of domed material or where material exhibits negative curling,
turn the test specimen over to measure inverted or with the back of the sample facing up. Measure
curling and mark appropriately as negative curling.
ISO 23999:2021(E)
5 Apparatus
5.1 Oven
The oven shall be thermostatically controlled and ventilated, capable of being maintained at a uniform
temperature of 80 °C ± 2 °C. If a temperature setting other than 80 °C is utilized, mark the test sheet as
appropriate and verify the oven’s capability to maintain a uniform temperature set point.
In operation, ensure that radiation from the heating element does not directly reach the test specimens
or support plates.
5.2 Support plates
The support plates shall be of metal, e.g. aluminium or stainless steel, of dimensions larger than the test
specimen and not less than 1,5 mm in thickness. Ensure that the support plates are kept smooth and
polished so that surface friction does not interfere with free shrinkage or growth of the test specimens.
The plates shall be flat and free of convex or concave distortion and fully support the sample (e.g. a wire
rack support plate is not acceptable.).
The shapes and dimensions of the apparatus specified in 5.1 and 5.2 shall be such that:
a) curling can be measured without removing the test specimens from the support plates, except in
the case of domed material or where material exhibits negative curling;
b) the distance between the plates and the vertical walls of the oven shall be more than 50 mm;
c) the vertical distance between the support plates and between the plates and the oven shall be more
than 100 mm.
5.3 Measuring device
5.3.1 Measuring equipment
The measuring equipment for sheet, tile and plank products, shall preferably be an optical bench for
non-contact dimensional stability measurements or block and dial gauge apparatus, see examples
shown in Figure 2, Figure 3 and Figure 4. The equipment shall have a range of at least 200 mm and a
precision of ± 0,02 mm. For many types of optical benches, ensure that
