This specification covers quality assurance sampling and testing procedures used to determine conformance to applicable specification requirements of wrought aluminum alloy and wrought magnesium alloy mill products (except forging stock), and includes quality assurance and testing procedures for rolled, forged, and flash welded rings (see 8.3). Requirements are specified in inch/pound units.
There are differences in how gauge ranges are published. How an ordered gauge between gauge break is treated can affect clad thickness, property limits, and testing location. The proposed revision to AMS2355 will require rounding according to ASTM E29 for ordered gauges having extra digits. The revision will provide consistency among the interpretations possible for all text used to specify a gauge range.
