Scope

This standard specifies the requirements, test method, procedure, result assessment,
quality grade, record and report of ultrasonic test for forged and rolled steel bars.
This standard is applicable to the forged and rolled steel bars whose diameter
(thickness) is 12mm ~ 200mm and is tested with ultrasonic (longitudinal wave or
transverse wave) impulse reflection method (contact method or immersion method);
this standard may also act as the reference for the test of other forged and rolled bars.
This standard is not applicable to austenite scorched steel bars.
