1 Scope This standard specifies acceptance levels for indications from surface breaking imperfections in metallic welds detected by penetrant testing. This standard is primarily intended for use during manufacture inspection, but where appropriate, it can be used for in-service inspection. The acceptance levels in this standard are based on detection capabilities that can be expected when using techniques specified in GB/T 18851.1 and parameters recommended in Appendix A. The acceptance levels can be related to welding standards, application standards, specifications or codes. More information relevant to acceptable levels of indications can be found in product or application standards. 2 Normative References The following documents are indispensable for the application of this standard. For dated references, only the dated edition is applicable to this document. For undated references, the latest editions of the normative documents (including all the amendments) are applicable to this document.
