Environmental Stress Crack Resistance of Polyethylene Today, this test is specified less frequently because it is not as aggressive towards modern resins. The Bent Strip test is a constant strain test, but polyethylene relaxes when strained. This stress relaxation allows testing to run without failure for very long periods (>1,500 hours).

Mar 01, 2016 · and environmental), cabinet corrosion testing can also be very effective as free iron detection tests. Free iron testing is an excellent predictor of corrosion resistance properties and surface finish success. Locations on a casting or finished part, which are rich in free iron, can become epicenters for corrosion while in service or inventory.
