Radiography Testing

Our Radiography Testing Service

Radiographic testing makes use of X-ray radiation to create images capable of showing defects hidden inside material up to two inches thick. This inspection is widely used to test the integrity of welds, castings, piping, machined parts, pressure vessels and other objects. No surface preparation is needed, and the results are later always viewable on the produced X-ray films.

GCE Radiography Testing Service is used for projects with the following specifications:

ASTM E-1742

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.

MIL-STD 453C

MIL-STD-453C, MILITARY STANDARD: INSPECTION, RADIOGRAPHIC (27 DEC 1984) [S/S BY ASTM-E1742] [SUPERSEDES MIL-STD-00453B & MIL-R-11470A] [S/S BY ASTM-E1742]., The purpose of this military standard is to prescribe the radiographic inspection requirements for metallic and nonmetallic materials.

NAVSEA T9074-AS-GIB-010/271

NAVSEA Technical Publication T9074-AS-GIB-010/271, Requirements for Nondestructive Testing Methods, was last revised in 1999 with the issuance of Advanced Change Notice 1 (dated 16 February 1999) and covers the requirements for conducting nondestructive testing (NDT) used in determining the presence of discontinuities in metals. It also contains the minimum requirements necessary to qualify NDT personnel, procedures, and equipment. The NAVSEA Chief Engineer’s (CHENG’s) intent for the changes in Revision 1 is to reduce non-destructive testing and evaluation (NDT&E) costs without reducing quality or capability.
