5.4.2 Nondestructive inspection

5.4.2.1 Penetrant Inspection

All Class A and B welds shall be inspected in accordance with ASTM-E1417, unless magnetic particle inspection is performed. Class C weld shall be inspected when specified on the drawing or in the contract.

5.4.2.2 Magnetic particle inspection

All Class A and B welds of ferromagnetic materials shall be inspected in accordance with ASTM-E1444 unless penetrant inspection is performed. Class C welds shall be inspected when specified on the drawing or in the contract.

5.4.2.3 Radiographic inspection

All Class A groove welds (except for fillet welds) or butt joints shall be inspected in accordance with ASTM-E1742. Class B and C welds shall be inspected radiographically per ASTM-E1742 when specified on the drawing or in the contract. Ultrasonic inspection (see 5.4.2.4) may be used in lieu of radiographic inspection when specified on the drawing or in the contract.

5.4.2.4 Ultrasonic inspection

Ultrasonic inspection in accordance with SAE-AMS-STD-2154 shall be performed when specified on the drawing or in the contract.

5.4.2.5 Extent of inspection

Unless otherwise specified in 5.4.2.1, 5.4.2.2, or 5.4.2.3, nondestructive inspection shall be performed within the following parameters to ensure that the requirements of 5.4.3.5 are met:
