Non-destructive testing of welds - Radiographic testing - Part 1: X- and gamma-ray techniques with film (ISO 17636-1:2022)

This document specifies techniques of radiographic testing of fusion-welded joints in metallic materials using industrial radiographic film techniques with the object of enabling satisfactory and repeatable results. The techniques are based on generally recognized practice and fundamental theory of the subject. It applies to the joints of plates and pipes in metallic materials. Besides its conventional meaning, “pipe” as used in this document covers other cylindrical bodies, such as tubes, penstocks, boiler drums and pressure vessels. This document does not specify acceptance levels for any of the indications found on the radiographs. The ISO 10675 series provides information on acceptance levels for weld evaluation. If contracting parties apply lower test criteria, it is possible that the quality achieved will be significantly lower than when this document is strictly applied.
