AIA/NAS 1434-2013 pdf download RADIOGRAPHIC STANDARDS FOR MAGNESIUM ALLOY CASTINGS
The casting radiographic quality grades shown herein may be called out on the engineering drawings and willthereby define the maximum acceptable limit for each class of defect in any desianated area. More than one cualitvgrade may be called out on any one casting drawing if separate areas are designated for each grade.
The reference film and grading numbers are based on ASTM E155 reference radiographs for inspection of aluminumand magnesium castings.
