33、cument 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 can be applied to other types of welds or materials.The acceptance levels can be related to welding stand
34、ards, application standards, specifications or codes. This document assumes that the radiographic testing has been carried out in accordance with ISO 17636-1 and ISO 17636-2.When assessing whether a weld meets the requirements specified for a weld quality level, the sizes of imperfections permitted
35、by standards are compared with the dimensions of indications revealed by a radiograph made of the weld.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
