The ISO 813 method is used to determine adhesive strength between a vulcanized or thermoplastic rubber to a rigid substrate. The test is performed at a peel angle of 90° with a speed of 50 mm/min. The adhered rubber is pulled from the rigid substrate to measure the adhesive strength, also known as the average force divided by the specimen width.

The challenges of testing to this standard are:

Maintaining 90° angle throughout the test
Bandwidth and data rate to capture peaks and troughs
Eliminating slippage throughout the test
