The value where the results change from mainly passing to mainly failing is the impact failure end point. For interlaboratory comparisons, rankings of coatings for impact resistance should be reported. Originally approved in Electronics and Electrical Testing Equipments. Useful for checking resistance to impact surface damage and penetration for construction materials viz plastic, In its use over many years, this test method for impact resistance has been found to be useful in predicting the performance of organic coatings for their ability to resist cracking caused by impacts.

The base is constructed so that a thin?
