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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 11638 was prepared by Technical Committee ISO/TC 219, Floor coverings.

INTERNATIONAL STANDARD ISO 11638:2012(E)
Resilient floor coverings — Heterogeneous poly(vinyl chloride)
flooring on foam — Specification
1 Scope
This International Standard specifies the characteristics of heterogeneous poly(vinyl chloride) flooring on
foam, based on poly(vinyl chloride), and supplied in roll form or tile. Such products can contain a transparent,
non-PVC factory finish.
To encourage the consumer to make an informed choice, this International Standard includes a classification system,
based on intensity of use, which shows where these floor coverings can be expected to give satisfactory service.
It also specifies requirements for marking.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
heterogeneous floor covering on foam
floor covering consisting of a wear layer and other solid layers on a foam backing
3.2
poly(vinyl chloride) floor coverings on foam
floor covering with surface layers which are produced using poly(vinyl chloride) as the binder
3.3
wear layer
layer of the floor covering directly exposed to wear
3.4
factory finish
transparent coating applied during the manufacture, usually not thicker than 0,05 mm
3.5
binder content
portion of the flooring composition consisting of poly(vinyl chloride) (PVC) resin, plasticizers and stabilizers
NOTE It is expressed as a percentage mass fraction of the total composition.
3.6
seam strength
