ASTM A578/A578M-17(2023)

Annotation of standard text ASTM A578/A578M-17(2023) :

This procedure covers the standard and acceptance standards for straight-beam, pulse-echo, ultrasonic examination of rolled carbon and alloy steel plates. The amplitude linearity of the apparatus to be used shall be checked by positioning the transducer over the depth resolution notch in the IIW or similar block. The inspection shall be performed in an area free of operations that interfere with proper performance of the test. The test shall be performed either by direct contact, immersion, or liquid column coupling. Grid scanning shall be conducted along a continuous perpendicular line on the center. All discontinuities causing complete loss of reflection shall be recorded.
