This European Standard specifies acceptance levels for indications from imperfections in butt welds of steel, nickel, titanium and their alloys detected by radiographic testing. 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. This European Standard assumes that the radiographic testing 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.
