This standard specifies the techniques for the manual ultrasonic testing of fusion-welded joints in metallic materials with thickness greater than or equal to 8 mm which exhibit low ultrasonic attenuation (especially that due to scatter) at object temperatures from 0 ~ 60 degree Celcius. It is primarily intended for use on full penetration welds where both the welded and parent material are ferritic.
