Rationale: AMS5670H is the result of a Five-Year Review and update of the specification. The revision updates the Title to match the Scope, revises composition testing and reporting requirements (see 3.1 and 3.1.1), adds conditions for larger bars (see 3.2.1.1.1), prohibits bars being cut from plates (see 3.2.1.2 and 4.4.5), clarifies heat treatment time (see 3.4.1.2), adds the option for additional requirements for forging stock (see 4.4.7 and 8.6), and updates the exception requirements (see 8.5).
