Sets out methods for the ultrasonic manual listing of carbon and low alloy wrought steel plate of uniform thickness, in the range 5 mm to 180 mm inclusive, using A-scan presentation. Four quality levels are specified in terms of limits in size of discontinuities.

This standard sets out methods for the ultrasonic manual testing of carbon and low alloy wrought steel plate of uniform thickness, in the range 5 mm to 180 mm inclusive, using A-scan presentation. It also classifies plate quality.NOTE: Supplementary information required to augment the standard is set out in Appendix A.
