It applies to joints in single wall pipes and plates with a range of thicknesses from 5 mm to 100 mm. It only applies to pipes containing air or other gases at the time of X-ray testing. This document does not specify acceptance levels of the indications. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

WARNING NOTICE - Exposure of any part of the human body to X-rays can be highly injurious to health. Wherever X-ray equipment is in use, appropriate legal requirements shall be applied.

5.2 Surface preparation and stage of manufacture Prior to radiography the joint shall be cleaned to remove all traces of dirt etc. from the component surface, which might later cause difficulty in detecting defects. In the case of heated tool butt welded pipes, the external weld bead shall be removed prior to radiography. SIST EN 13100-2:2005

EN 13100-2:2004 (E) 6 5.3 Location of the weld in the radiograph Where the weld is not likely to be clearly visible on the radiograph, high-density markers (e.g. lead) shall be placed on either side of the weld before testing. 5.4 Identification of radiographs Symbols (normally lead markers) shall be affixed to each section of the object being radiographed. The images of these symbols shall appear in the radiograph outside the region of interest and shall ensure unambiguous identification of the section. 5.5 Marking Permanent markings on the object to be examined shall be made in order to accurately locate the position of each radiograph. Where the nature of the material and/or its service conditions do not permit permanent marking, the location of each radiograph may be recorded by means of accurate sketches. 5.6 Overlap of films When radiographing an area with two or more separate films, the films shall overlap sufficiently to ensure that the complete region of interest is radiographed. This shall be verified by a high-density marker on the surface of the object, which will appear on each film. 5.7 Types and position of image quality indicators (IQI) The quality of image shall be verified by use of image quality indicator(s) (IQI) in accordance with EN 462-1 or EN 462-2. The IQI(s) shall be made from the same material as the inspected material or a material with a similar absorption with a tolerance of ± 10 % in the absorption coefficient.
