1.1 This International Standard specifies a method of exposing test specimens of plastic materials, free from all external restraint, to liquid chemicals, and methods for determining the changes in properties resulting from such immersion. It does not cover environmental stress cracking (ESC) which is dealt with by ISO 4599, ISO 4600 and ISO 6252.
1.2 It only considers testing by immersion of the entire surface of the test specimen.1) NOTE This method may not be appropriate for simulating partial or infrequent wetting of plastics.
1.3 It is applicable to all solid plastics that are available in the form of moulding or extrusion materials, plates, tubes, rods or sheets having a thickness greater than 0,1 mm. It is not applicable to cellular materials.
