BS EN 60953-2:1996 is a British Standard that specifies the acceptance criteria for radiographic examination of fusion welded joints in metallic materials. Specifically, it outlines the requirements for the quality levels of imperfections in the radiographic images of welds.
The standard applies to metallic materials that are welded using fusion welding processes, such as gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), and shielded metal arc welding (SMAW). It is applicable to butt welds, fillet welds, and branch connections.
BS EN 60953-2:1996 provides a set of criteria for assessing the quality of radiographic images of welds, based on the size and type of the imperfections detected. The standard also provides guidance on the use of different types of radiographic techniques and equipment for different types of materials and welds.
Overall, the standard helps to ensure that radiographic examination of welded joints is carried out in a consistent and reliable manner, and that the quality of the welds is assessed according to internationally recognized standards.
