Additional information

Significance and Use

4.1 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 E1030, E1032, and E1416 contain information to help develop detailed technique/procedure requirements.

1. Scope

1.1 This practice2 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 Optical 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 either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
