This European Standard specifies fundamental techniques of radiography with the object of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on generally recognized practice and fundamental theory of the subject. This standard applies to the radiographic examination of fusion welded joints in metallic materials. It applies to the joints of plates or pipes. Besides its conventional meaning, "pipe" as used in this standard should be understood to cover other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels. This standard compies with EN 444. This standard does not specify acceptance levels of the indications. If contracting parties apply lower test criteria, the quality achieved may be significantly lower than when this standard is stricly applied.
