WARNING: This International Sandard may involve hazardous materials, operations and equipment. It does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.1 This International Standard describes procedures for constant immersion accelerated exfoliation corrosion testing of aluminium alloys primarily for the purpose of research, development and quality control. 1.2 It covers aspects of the corrosive solution, specimen preparation, exposure, inspection and interpretation of test results. 1.3 This International Standard is applicable primarily to the testing of wrought aluminium alloys in the form of semi-finished mill products and parts produced both from conventional ingot metallurgy processes and from powder metallurgy processes, as well as aluminium alloy metal matrix composites including those produced by mechanical alloying. 1.4 It can also be used for testing ingots and cast aluminium alloys when oriented structures such as columnar grains or striated segregations are present. 1.5 The results of these tests are most applicable to research studies of trends in alloy development and should not be considered as an absolute criterion of the resistance to exfoliation. When these tests are used for production control of exfoliation-resistant materials, limits of acceptable performance should be the subject of an agreement between concerned parties.
