ISO 36-2017 pdf free.Rubber, vulcanized or thermoplastic一Determination of adhesion to texti le fabrics.
The stripping force required to separate two plies of fabric bonded with rubber, or a rubber layer and a fabric ply bonded together, is measured under specified conditions using test pieces of standard dimensions in the form ola flat strip.
S 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. An inertialess dynamometer (of the electronic or optical type, for example) should preferably be used.
The machine shall comply with the requirements of ISO 5893. be capable of measuring force with an accuracy corresponding to class 1 as defined in ISO 5893:2002, and have a rate of traverse of the moving grip of 50 mm/mm ± 5 mm/mm.
The machine shall be fitted with grips capable of holding the test piece and the ply to be separated without slipping during the test.
5.2 Autographlc recorder, with a scale sufficiently large to permit easy interpretation of the trace, or computer with graphic capabilities and software enabling it to comply with the procedure for data processing described in ISO 6133.
6 Calibration
The test apparatus shall be calibrated in accordance with the schedule given in Annex A.
7 Test piece
The test piece shall have a width of 25 mm ± 0,5 mm and shall be of sufficient length to permit ply separation during measurement over a length of at least 100 mm. The minimum thickness of the constituent components, or of one of them, shall be such that the weakest component can transmit the force necessary for separation without breaking.
The test piece shall be cut in a plane parallel to the warp in the length direction and parallel to the weft in the width direction.
If required, also cut test pieces in a plane parallel to the weft in the length direction and parallel to the warp in the width direction.
If there is a danger of bits of fabric being removed from the test piece due to irregularity of fabric alignment, make the test pieces slightly wider, but at least the ply to be stripped shall be cut to the width of 25 mm.ISO 36 pdf free download.
