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.

Resilient floor coverings — Specification for floor
coverings based on thermoplastic polymers
1 Scope
This document specifies the characteristics for resilient floor coverings based upon thermoplastic
polymers, supplied either in roll, plank or tile form.
To encourage the consumer to make an informed choice, this document includes a classification
system (see ISO 10874) based on intensity of use, which shows where these floor coverings should give
satisfactory service. It also specifies requirements for marking.
This specification does not apply to floor coverings specified in ISO 10581, ISO 10582, ISO 10595,
ISO 11638, ISO 10575, ISO 10577, ISO 24011 and ISO 26986.

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:
— IEC Electropedia: available at http:// www .electropedia .org/
— ISO Online browsing platform: available at http:// www .iso .org/ obp
3.1
homogeneous floor covering
floor covering with one or more layers of the same composition and colour, patterned throughout its
thickness
3.2
heterogeneous floor covering
floor covering consisting of a wear layer (3.8) and other layer(s) which differ in composition and/or
design and can contain a reinforcement
3.3
factory finish
transparent coating applied during the manufacture, usually not thicker than 0,03 mm not using
thermoplastic polymer (3.6) as base resin
Note 1 to entry: This coating should not be counted as part of the wear layer (3.8).
3.4
product with backing
homogeneous (3.1) or a heterogeneous floor covering (3.2) with a backing of any material different from
the upper layers or a backing made with a foamed layer
Note 1 to entry: Typical example backings include materials such as cork, foams, polyester or jute.
3.5
scratch
permanent damage or mark on the surface of the floor covering made with a sharp or pointed object
3.6
thermoplastic polymer
polymers that become liquid when heated above Tg (glass transition temperature) or Tm (melting
temperature) and return to the solid state when cooled
Note 1 to entry: This cycle of melting and freezing can be repeated.
3.7
plank
tile with a ratio length divided by width superior or equal to 1,3
3.8
wear layer
portion of a resilient floor covering that contains or protects the pattern and design exclusive of
temporary factory finishes (3.3) or maintenance coating(s)
