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

Introduction
When ISO/TC 38/SC 12 reviewed ISO 2551:1981, it decided that because the original method gave rise to
technical difficulties, any revision should incorporate a number of test method options for dimensional
stability to heat, water and combined heat, and water and stability out of the plane. In order to establish
the utility of this new approach, and to allow the precision of each test method to be established, it was
decided to initially publish a document that would allow for further development based on some or all
of these methods.
INTERNATIONAL STANDARD ISO 17984:2014(E)
Machine-made textile floor coverings — Determination of
dimensional changes after exposure to heat and/or water
1 Scope
This International Standard specifies procedures for the determination of both planar and out-of-plane
dimensional changes that take place when machine-made textile floor coverings are subjected to heat,
water, or varied heat and water conditions.
The following methods are applicable to all machine-made textile floor coverings including those
produced in tile form.
— Method 1: Determination of dimensional changes after exposure to heat.
— Method 2: Determination of dimensional changes after immersion in water.
— Method 3: Determination of dimensional changes due to the effects of varied heat and water
conditions.
— Method 4: Dimensional changes out of the plane.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 1957, Machine-made textile floor coverings — Selection and cutting of specimens for physical tests
ISO 2424, Textile floor coverings — Vocabulary
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO 2424 apply.
4 Principle
Comparison is made between either planar or out-of-plane dimensions of a test specimen after
conditioning in the standard atmosphere for testing textiles and after being subjected to either heat,
water, or specified varied heat and water conditions.
5 Apparatus
5.1 Methods 1, 2, and 3
5.1.1 Instrument capable of measuring length to the nearest 0,1 mm, e.g. an optical bench or
mechanical device with gauge.
5.1.2 Plate glass sheet, marginally smaller than the test specimen, or other means of keeping the
specimen flat while measurements are made.
This will not be required if the instrument in 5.1.1 incorporates such a glass or metal plate.
5.1.3 Steel pins or other appropriate means of indicating the reference points on the test
specimen, if necessary.
NOTE A suitable piece of equipment incorporating 5.1.1, 5.1.2, and 5.1.3 is given in Annex A.
5.2 Methods 1 and 3
5.2.1 Ventilated drying oven, capable of being controlled at 60 °C ± 2 °C, with perforated and lacquered
shelves that can be placed in the oven.
5.2.2 Desiccator or similar apparatus, for maintaining specimens in a dry condition.
5.3 Methods 2 and 3
5.3.1 Container, for holding water at 20 °C ± 2 °C, with dimensions at least 20 mm greater than the test
specimen and deep enough to accommodate the submerged test specimen.
5.3.2 Rigid perforated tray, of a sufficient size to carry the test specimen.
5.3.3 Efficient wetting agent, e.g. sodium dioctyl sulfosuccinate or dodecylbenzene sodium sulfonate.
5.3.4 Means of ensuring a forced draught of ambient air, if required.
5.4 Method 4 (if used in conjunction with methods 1, 2, or 3)
5.4.1 Gauge or instrument, capable of measuring in the vertical dimension, to an accuracy of 0,5 mm.
6 Sampling and selection of test specimens
6.1 Sampling
Select the specimens in accordance with ISO 1957.
6.2 Number and dimensions of test specimens
Take at least three test specimens each measuring not less than 450 mm × 450 mm, noting the direction
of manufacture.
6.3 Conditioning
Lay out the specimens flat, singly and with the use surface uppermost in the standard atmosphere for
testing for at least 48 h and until they reach constant mass (define
