Principle:
Peel cling testing requires two different types of samples. The first sample is larger piece as backing placed on test bed. The second piece is a smaller strip which is peeled off the larger sample.
The larger sample is wrapped fixed on the incline surface and the smaller sample is attached to a clip, connected with loadcell. It's pulled after it's clung to the large sample and the force is measured during the pulling.
We recommend the way described in ASTM D5458, which, during the test, reduces the influence of frictions in a tensile tester and pulley.
It complies with ASTM D 5458, BB/T 0024.
