ASTM E709: standard practice for magnetic particle testing;
ASTM E23: standard methods for notched bar impact testing of metallic materials.
General
All standard steel forgings shall be examined for both surface breaking and totally enclosed internal defects. Non-destructive examination shall take place after the completion of all heat treatment.
Surface Defects
The outside surface of each standard steel bar or tube shall be inspected for defects. The preferred methods are either the Ultrasonic (UT) or Magnetic Particle (MT) methods. As an option, other methods (such as eddy current) may be used, providing it can be demonstrated that the system and procedure are capable of detecting indications described in Table A.16.
The inside surface of each tube shall be inspected for defects by the ultrasonic (UT) angle-beam (shear wave) method. This requirement applies only to materials that are identifiable as tubes before heat treatment. Materials that are heat-treated are not considered tubes, for inspection purposes.
