The ESCR Test Apparatus is used to gauge a material's resistance to cracking brought on by environmental stress. In order to conduct the test, a sample of the material is typically subjected to a combination of stress and a particular environment, such as tensile stress combined with a particular liquid or chemical. The results, which are typically expressed in terms of the amount of time needed for a crack to form in the sample, can be used to assess a material's suitability for use in particular conditions or circumstances. In the plastics industry, ESCR test equipment is frequently used to assess how well materials perform in various environmental conditions. We have best method for this test which is the ASTM D1693.
