Peel Strength Testing, solar specialized laboratory tests
Peel Strength testing is a simple mechanical test method which measures the peel separation strength of two flexible materials which have been adhered or bonded together. It is also known as the " T-Peel " test because of the sample shape, which resembles the letter "T" when the sample is loaded on the machine before the peel testing.
