3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
adhesion strength force per unit width required to cause a separation at the interface between the assembled components
NOTE Any separation occurring at any other point, for example inside either component under test, is a failure of the component material, and does not indicate an adhesion strength. In such cases, the adhesion strength is greater than the strength of the weakest component involved.
4 Principle
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 of a flat strip.
5 Apparatus
5.1 Test machine, power-driven and equipped with a suitable dynarnometer; 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 2, as defined in ISO 5893:2002, and have a rate of traverse of the moving grip of 50 mm/rn in ± 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 Autographic 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 Test piece
6.1 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 thickness shall be suitably reduced (see ISO 23529), if necessary, in order to ensure that the line of separation of the plies during the test lies as close as possible to the plane of the strips of test piece held in the grips (see Figure 1). For tests intended to be comparable, the test pieces shall have the same dimensions.ISO 36 pdf download.
