This International Standard specifies a method for the determination of environmental stress cracking (ESC) resistance of thermoplastics by means of a constant strain test. ESC will be indicated by the change of a suitably chosen indicative property of specimens that have been strained for a defined time in the environment. The method of test is suitable for determining the resistance of sheets and of flat test specimens to environmental stress cracking, especially the sensitivity of localized surface region of specimens to ESC. For the determination of the ESC sensitivity of finished articles or the bulk of a material subjected to a constant tensile strain, see ISO 22088-5. The bent strip method is suitable for the determination of ESC caused by gases and liquids as well as solids containing migrating substances (e.g. polymeric adhesives and materials containing plasticizers) in contact with a specific polymer. Preferably, this method is used to determine the ESC resistance of rigid plastics that exhibit only moderate stress relaxation during the time of the test. For a constant strain test, refer to ISO 22088-5. For a constant stress test, refer to ISO 22088-2.
