This standard specifies requirements for full peripheral ultrasonic shear wave testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of longitudinal imperfections according to four different acceptance levels (see table 1). This standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 9 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5. For tubes with an outside diameter-to-thickness ratio less than 5, one of the methods specified in Annex A shall be used by agreement between manufacturer and purchaser.
