Steel Cleanliness, Special Aircraft-Quality Magnetic Particle Inspection Procedure
AMS2304C
This specification covers steel cleanliness requirements in inch/pound units for special aircraft-quality ferromagnetic steels, including hardenable corrosion resistant steels, by magnetic particle inspection methods. This specification contains sampling, sample preparation, inspection procedures and cleanliness rating criteria (see 8.2).
Rationale:
AMS2304C results from a Five-Year Review and update of this document, allows periodic testing by adding 4.2.3, 4.2.3.1, 4.2.3.2, 4.2.3.3, and 8.8 that cover the process qualification, testing frequency, historical data and melting-casting process controls.
