1 Scope

The standard provides for rapid discovery of magnetostrictive ultrasonic guided wave testing method for the presence of a member of the section loss. This standard applies to the detected temperature of -20 ℃ ~ 550 ℃, diameter of 10mm ~ 1000mm, wall thickness of 0.5mm ~ 80mm Tube diameter of 10mm ~ 80mm rod diameter and surface and internal defects 10mm ~ 185mm wispy and other components. If combined With the consent of the parties, it may be applied to the detection of said member or other member of the butt weld. This standard does not establish the evaluation criterion, specific criteria determined by the parties to the contract negotiations. This standard does not fully given when the safety requirements for testing, the use of this standard to establish appropriate safety obligation of the parties prior to detection And protection guidelines.
