Steel Cleanliness, Aircraft Quality Magnetic Particle Inspection Procedure
This specification covers steel cleanliness requirements in inch/pound units for aircraft-quality ferro-magnetic steels, other than hardenable corrosion resistant steels (See AMS2303), by magnetic particle inspection methods. This specification contains sampling, specimen preparation, inspection procedures and cleanliness rating criteria (See 8.5).
The metric version, MAM2301, has been cancelled. The SI units have been included in this specification, but the inch/pound units are primary (See 8.5).
