I am confused by 3.3.6 and 3.3.7 requirements for peening time. Per 3.3.6, parts shall be shot peened "using the same...time...as used on the test strip." On the other hand, per 3.3.7, "parts...shall be peened to complete visual coverage." It seems to be common knowledge that aluminum alloys reach full coverage faster than steel, so these requirements appear to conflict. We have been specifying that the coverage requirement rules (i.e., peening times on aluminum parts can be lower than T1). But how will an auditor view this?
