This test method covers the determination of the comparative peel or stripping characteristics of adhesive bonds when tested on standard sized specimens and under defined conditions of pretreatment, temperature, and testing machine speed. This is a tensile test of either flexible or rigid material, where specimens are 25 mm (1 inch) wide. Typical results include average load divided by specimen width.
We recommend performing this test on single column or dual column test frames equipped with pneumatic or manual screw action grips with rubber coated or smooth flat faces. You may use an alignment plate with the grip to maintain the same plane for the specimen during the test.
It's important to consider data acquisition. For this, your testing system will need a uniform, high data sampling rate to ensure that the test peaks and troughs are captured for an accurate average load calculation.
Bandwidth plays a critical role. Too high of a bandwidth allows noise to compromise the readings, while too low of a bandwidth may "dull" the system and lead to missed peaks and troughs (resulting in lower average load values).
It is important to read and review ASTM D903 in order to fully understand the test set up, procedures, and results requirements.
