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 26082-2 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 289, Leather, in collaboration with the Physical Tests Commission of the International Union of
Leather Technologists and Chemists Societies (IUP Commission, IULTCS) in accordance with the agreement
on technical cooperation between ISO and CEN (Vienna Agreement).
IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to further the
advancement of leather science and technology. IULTCS has three Commissions, which are responsible for
establishing international methods for sampling and the testing of leather. ISO recognizes IULTCS as an
international standardizing body for the preparation of test methods for leather.
ISO 26082 consists of the following parts, under the general title Leather — Physical and mechanical test
methods for the determination of soiling:
Part 1: Rubbing (Martindale) method
Part 2: Tumbling method

Tumbling method
1 Scope
This part of ISO 26082 specifies a tumbling method which is intended to determine the resistance of all forms
of leather to visible soiling through repeated contact with soiled objects. It provides a physical pretreatment
routine for leathers that may be vulnerable to loss of soiling resistance in service.

Part 1: Martindale abrasion testing apparatus
3 Principle
A controlled soiling treatment comprising multiple impacts with soiled felt pads is applied to a specimen. This
is achieved by tumbling the felt pads within a rotating container into one end of which the specimen is fixed.
The change in colour of a standard fabric fixed at the other end of the rotating cylinder is used to determine
the end-point of the soiling treatment. A pretreatment to simulate wear may be applied to leathers that are
vulnerable to a loss of soiling resistance in service.
