ASTM E1742-08a

Standard Practice for Radiographic Examination

SIGNIFICANCE AND USE
This practice establishes the basic parameters for the application and control of the radiographic method. This practice is written so it can be specified on the engineering drawing, specification, or contract. It is not a detailed how-to procedure to be used by the NDT facility and, therefore, must be supplemented by a detailed procedure (see 6.1). Test Methods E 1030, E 1032, and E 1416 contain information to help develop detailed technique/procedure requirements.
SCOPE
1.1 This practice establishes the minimum requirements for radiographic examination for metallic and nonmetallic materials.  
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 items should be addressed in the purchase order or the contract.
1.3.1 DoD contracts.
1.3.2 Personnel qualification, 5.1.1.
1.3.3 Agency qualification, 5.1.2.
1.3.4 Digitizing techniques, 5.4.5.
1.3.5 Alternate image quality indicator (IQI) types, 5.5.3.
1.3.6 Examination sequence, 6.6.
1.3.7 Non-film techniques, 6.7.
1.3.8 Radiographic quality levels, 6.9.
1.3.9 Film density, 6.10.
1.3.10 IQI qualification exposure, 6.13.3.
1.3.11 Non-requirement for IQI, 6.18.
1.3.12 Examination coverage for welds, A2.2.2.
1.3.13 Electron beam welds, A2.3.
1.3.14 Geometric unsharpness, 6.23.
1.3.15 Responsibility for examination, 6.27.1.
1.3.16 Examination report, 6.27.2.
1.3.17 Retention of radiographs, 6.27.8.
1.3.18 Storage of radiographs, 6.27.9.
1.3.19 Reproduction of radiographs, 6.27.10 and 6.27.10.1.
1.3.20 Acceptable parts, 6.28.1.
1.4 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
