BAS EN 12517/A2:2004

This standard specifies acceptance levels for indications from imperfections in steel butt welds detected by radiography . If agreed, the acceptance levels may be applied to other types of welds or materials. The acceptance levels may be related to welding standards, application standards, specifications or codes. Such a relationship is shown in EN 12062 for EN 25817. This standard assumes that the radiographic examination has been carried out in accordance with EN 1435. 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.
