    1. Scope

    1.1 This stress corrosion practice is intended for statically loaded smooth non-welded or welded specimen tests of 7XXX series Al-Zn-Mg alloys containing less than 0.26% copper.

    1.2 This practice is concerned primarily with the test medium which may be used with a variety of test specimens and methods for applying stress. Exposure times, criteria of failure, and so on, are variable and not specified.

    1.3 This standard does not purport to address all of the safety concerns, if any, 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. See Section 8 for additional precautions.
