    Abstract

    As special heat treatments to improve resistance of aluminum alloys to exfoliation were developed, the need for accelerated testing methods to control production heat treatment arose. A joint task group formed by ASTM Committee GO1.05 and the Aluminum Association has conducted an interlaboratory testing program of various salt spray and immersion tests for 7000 series alloys. A constant immersion test produced the best results.
