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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
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 www.iso.org/iso/foreword.html.
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 and textile
floor coverings, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna
Agreement).
This fourth edition cancels and replaces the third edition (ISO 24342:2018), which has been technically
revised.
The main changes are as follows:
— procedures have been modified to allow for differences between planks and tiles. Clauses 3, 4, 5, 8 and 9
have therefore been updated;
— uncertainty of measurement of the records defined by dial gauges method has been changed from 0,02
mm into 0,01 mm.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Resilient and textile floor coverings — Determination of side
length, edge straightness and squareness of tiles and planks
1 Scope
This document specifies methods for determining side lengths, straightness of edges and squareness of
square and/or rectangular resilient or textile floor tiles and planks.
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:

— IEC Electropedia: available at https:// www .electropedia .org/
3.1
squareness
measurement of the amount the corner of the tile/plank deviates from 90°
Note 1 to entry: See Figure 1.
Figure 1 — Definition of squareness
3.2
straightness
property of an edge to be straight, unbent
Note 1 to entry: Some examples are shown in Figure 2.

3.3
tile
plank
type of resilient or textile flooring of predetermined shape intended to be used in a modular mode
Note 1 to entry: Tiles are usually square. Planks have a ratio length divided by width superior or equal to 1,3. A
modular product with a ratio inferior to 1,3 has to be considered as a tile.
4 Principle
The side lengths, straightness and squareness of resilient or textile floor tiles and planks are important
considerations because installed flooring will have an objectionable appearance if these performance
criteria are not followed. This can cause the installed tiles/planks to line up unevenly, producing unsightly
seams and corners that do not match. The surface dimensions of a tile/plank are measured by a contact
method at defined positions in each direction.
To assess the squareness of a tile, each corner of a right-angled tile is fitted into the dihedral angle of a
precision square and th
