Standard Practice for Radiographic Examination
|Publication Date:||10 October 1995|
1.1 This practice establishes the minimum requirements for radiographic examination for metallic and nonmetallic materials.
NOTE 1--When coordinated through the Department of Defense (DoD), this practice is intended as a direct replacement of MIL-STD-453.
1.2 Applicability--The criteria for the radiographic examination in this practice are applicable to all types of metallic and nonmetallic materials. The requirements expressed in this practice are intended to control the quality of the radiographic images and are not intended to establish acceptance criteria for parts and materials.
1.3 Basis of Application--There are areas in this practice that may require agreement between the cognizant engineering organization and the supplier, or specific direction from the cognizant engineering organization. These areas are identified as follows:
1.3.1 DoD contracts, 2.9.
1.3.2 Personnel qualification, 5.1.1.
1.3.3 Agency qualification, 5.1.2.
