This standard specifies the method to inspect wrought aluminum alloy by ultrasonic pulse reflection technology. The contents include the requirements for inspectors and inspection devices, inspection procedures, acceptance quality grade, inspection record and report, etc.
1.2 Application scope
This standard is applicable to the Ultrasonic inspection of such wrought aluminum alloy products as the following plates, section bars, forgings, bars and their spare parts. It is not applicable to the Ultrasonic inspection of casts, welding parts and sandwich construction.
Plates- the sawed and trimmed rolling material in a thickness larger than or equal to 10mm and possessing a rectangular cross section.
Section bars - the variety except for sheets, thick plates, shaped rods and wire rods; wrought materials whose cross-sectional area is larger than or equal to 70cm2, wall thickness is larger than or equal to 10mm and the length is quite larger than the cross-sectional area line.
Forgings - a general term for die forgings, free forgings and ring forgings. The forgings whose wall thickness is larger than or equal to 10mm and the maximum thickness is less than 300mm.
Rods - a general term for squeezed circular, square and hexagonal rough rods or finished rods with the diameter of the incircle larger than or equal to 25.0 mm.
