Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work of
preparing International Standards is normally carried out through IS0
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. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
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.
International Standard IS0 5981 was prepared by Technical Committee
ISOAC 45, Rubber and rubber products.
This second edition cancels and replaces the first edition (IS0 5981:1982),
which has been technically revised.

Rubber- or plastics-coated fabrics - Determination of resistance
to combined shear flexing and rubbing
WARNING - Persons using this International Standard should be familiar with normal laboratory practice.
This standard does not purport to address all of the safety problems, if any, associated with its use.
It is the responsibility of the user to establish appropriate safety and health practices and to ensure
compliance with any national regulatory conditions.
1 Scope
This International Standard specifies two methods of evaluating the resistance to combined shear flexing and
rubbing of rubber- or plastics-coated fabrics. Rubbing is either forced by application of a pressure foot (method A),
or is caused by simple contact between the faces of the test pieces (method B).
Method B (without application of the pressure foot) is preferred in all cases where the foot would damage the test
piece through an abrasive effect, e.g. materials with sticky surfaces, light coatings such as polyurethanes on rough
surfaces.
The test may be carried out on products as delivered or after pre-treatments such as wetting or accelerated ageing.
NOTE - The results using method A and method B should not be compared as there is no correlation between the two
methods.

3 Principle
A test piece is subjected to a succession of mild abrasive rubs applied to a continuously changing pattern of folds
created by a rubbing machine. The damage caused to the test piece is assessed visually.
4 Apparatus
4.1 General
The apparatus shall consist of a rubbing machine (see figures 1 and 2) having two parallel clamps giving contra-
reciprocating motions defined by their length and width, and a foot (optional) pressing on the flexing part of the test
piece.
The apparatus shall be equipped with a counter and a device making it possible to bring the two clamps into
juxtaposition manually.
Most counters, because of their method of drive, record only one impulse for one back and forth movement of the
clamps, i.e. two rubbings. In this case, the number indicated by the counter shall be multiplied by 2 in order to obtain
the number of rubbings (example: counter at 1 000, number of corresponding rubbings 2 000).
The components of the rubbing machine shall comply with the requirements specified in 4.2, 4.3 and 4.4.
