EN ISO 17636-1 Non-Destructive Testing of Welds - Radiographic Examination - Part 1: Film X and Gamma Ray Techniques

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN ISO 17636-1 testing. This standard covers radiographic testing techniques for fusion welded joints in metallic materials using industrial radiographic film techniques to provide satisfactory and reproducible results. The techniques are based on generally accepted practice and fundamental theory of the subject.

It is applied to the joints of plates and pipes in metallic materials. In addition to its conventional meaning, "pipe" used in this standard also includes other cylindrical bodies such as pipes, penstocks, boiler drums and pressure vessels.

This standard does not specify acceptance levels for any symptom found on radiographs. The ISO 10675 series provides information on acceptance levels for resource assessment. If the contracting parties apply lower test criteria, it is possible that the quality achieved will be significantly lower than when this standard is strictly enforced.

This standard specifies the basic techniques of radiography to provide satisfactory and reproducible results. The techniques are based on generally accepted practice and fundamental theory of the subject, the study of fusion welded joints with industrial radiographic films.

Generally, surface preparation is not required, but where surface imperfections or coatings may make it difficult to detect defects, the surface should be leveled or coatings removed.

Symbols should be affixed to each part of the radiographed object. Images of these symbols should appear on the radiograph, if possible outside the relevant region, and should provide a clear definition of the cross-section.

When radiographing an area with two or more separate films, the films must overlap sufficiently to ensure that the entire region of interest is radiographed. This will be confirmed by a high-density marker on the surface of the object that will appear in each movie.
