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 11379 was prepared by Technical Committee ISO/TC 219, Floor coverings.
This second edition cancels and replaces the first edition (ISO 11379:1997), which has been technically
revised.
INTERNATIONAL STANDARD ISO 11379:2009(E)

Textile floor coverings — Laboratory cleaning procedure using
spray extraction
1 Scope
This International Standard describes a laboratory-scale textile-floor-covering cleaning procedure using a
spray-extraction technique. This International Standard is applicable to all kinds of textile floor coverings, both
machine-made and hand-made.
NOTE Depending on the characteristic under investigation, test specimens subjected to this cleaning procedure can
be evaluated for many properties, e.g. ease of soil (dirt) removal, changes in appearance, effects of cleaning materials
and durability of floor covering finishes.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 139, Textiles — Standard atmospheres for conditioning and testing
ISO 1957, Machine-made textile floor coverings — Selection and cutting of specimens for physical tests
3 Principle
Test specimens of textile floor coverings are treated in a controlled manner with a spray-extraction cleaning
machine.
4 Apparatus and materials
4.1 Spray-extraction cleaning machine, capable of applying (3,75 ± 0,25) l/m of cleaning solution to the
surface when the cleaner wand is moved across the surface at a rate of (40 ± 5) mm/s.
