ISO 813 – Adhesion Strength of Rubber to Rigid Substrates

Description

ISO 813 – Adhesion Strength of Rubber to Rigid Substrates

 

ISO 813  specifies a method for the determination of the adhesive strength of a vulcanized or thermoplastic rubber bonded to a rigid substrate, using a test piece

comprising a strip of rubber bonded to a single plate of rigid material.

The test is performed at a peel angle of 90° with a speed of 50 mm/min

The method is applicable primarily to test pieces prepared in the laboratory under standard conditions, such as can be used to provide data for the choice of rubber

compounds or adhesive systems, the development of such materials and the control of manufacturing processes.

*** This method is not suitable for high-hardness rubbers, typically above 85 IRHD.

The 90° peel fixture is able to maintain this angle by using a low force sliding table that is adjusted throughout the test.

The fixture consists of a bearing mounted table, which is linked to the test system via a cable and pulley, as well as anchored on the back by a dampening coil spring.

As the crosshead is driven in the tensile direction, the cable pulls the table to maintain a constant 90° angle peel, and the coil spring keeps the table from reacting

to inertia caused by load peaks and troughs.

*** This fixture is adaptable for both single and dual column frames.

*** Before conducting ISO 813  ,  it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
