This document specifies acceptance levels for indications from imperfections in aluminium butt welds detected by radiographic testing. If agreed, the acceptance levels can be applied to other types of welds (such as fillet welds etc.) or materials.

The acceptance levels can be related to welding standards, application standards, specifications or codes. This document assumes that the radiographic testing has been carried out in accordance with ISO 17636-1 for RT-F (F = film) or ISO 17636-2 for RT-S (S = radioscopy) and RT-D (D = digital detectors).

When assessing whether a weld meets the requirements specified for a weld quality level, the sizes of imperfections permitted by standards are compared with the dimensions of indications revealed by a radiograph made of the weld.

This document specifies techniques of radiographic examination of fusion welded joints in metallic materials using industrial radiographic film techniques.
This document applies to the joints of plates and pipes. Besides its conventional meaning, “pipe” as used in this document it covers other cylindrical bodies such as tubes, penstocks, boiler drums, and pressure vessels.
NOTE This document complies with most requirements of ISO 5579 [1].
This document 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 this document is strictly applied.
