ISO 17636-1:2013 specifies techniques of radiographic examination of fusion welded joints in metallic materials using industrial radiographic film techniques.ISO 17636-1:2013 applies to the joints of plates and pipes. Besides its conventional meaning, "pipe" as used in this International Standard covers other cylindrical bodies such as tubes, penstocks, boiler drums, and pressure vessels.ISO 17636-1:2013 does not specify acceptance levels for any of the indications found on the radiographs.If contracting parties apply lower test criteria, it is possible that the quality achieved is significantly lower than when ISO 17636-1:2013 is strictly applied.
