Steel Cleanliness, Aircraft Quality Magnetic Particle Inspection Procedure
AMS2301L
This specification covers steel cleanliness requirements in inch/pound units for aircraft-quality ferro-magnetic steels, other than hardenable corrosion resistant steels (refer to AMS2303), by magnetic particle inspection methods. This specification contains sampling, specimen preparation, inspection procedures and cleanliness rating criteria (see 8.5).
Rationale:
AMS2301L results from a Five-Year Review and update of this document that allows periodic testing by adding 4.2.3, 4.2.3.1, 4.2.3.2, 4.2.3.3, and 8.6 that cover the process qualification, testing frequency, historical data, and melting-casting process controls.
