ISO 36:2020 pdf free download.Rubber, vulcanized or thermoplastic — Determination of adhesion to textile fabrics.
ISO 36:2020 specifies a method of test for measuring the force required to separate, by stripping, two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together.
ISO 36:2020 is applicable when the ply surfaces are approximately plane or when they are in the form of a cylinder having an internal diameter greater than approximately 50 mm. The method is not applicable when the ply surfaces contain sharp bends, angles or other gross irregularities which cannot be excluded when cutting out test pieces.
ISO 36:2020 does not apply to coated fabrics, which are tested in accordance with ISO 2411, or textile conveyor belts, which are tested in accordance with ISO 252.

4 Principle
The stripping force required to separate two plies of fabric bonded with rubber, or a rubber laye and a fabric ply bonded together, is measured under specified conditions using test pieces of standard dimensions in the form of a flat strip.
5 Apparatus
5.1 Test machine, power-driven and equipped with a suitable dynamometer; it shall be capable of maintaining a substantially constant rate of traverse of the moving head during the test and shall be linked to an autographic recorder or a computer with graphic capabilities for data acquisition and processing. A dynamometer without inertia (e.g. of the electronic or optical type ) should preferably be used.
The machine shall comply with the requirements of IS0 5893, be capable of measuring force with an accuracy corresponding to class 1 as defined in ISO 5893: 2019, and have a rate of traverse of the moving grip of 50 mm/min +5 mm/min.
The machine shall be fitted with grips capable of holding the test piece and the ply to be separated without slipping during the test.
