JB/T 9020-2018 is the English-translated version of 大型锻造曲轴的超声检测.
Ultrasonic testing of large forged crankshafts is the subject of JB/T 9020-2018, a recommended standard of the Chinese machinery industry. It states the requirements for the personnel who carry out the examination and for the equipment they use, sets out the testing methods, and gives the acceptance requirements against which the results are judged.
Forged crankshafts for diesel locomotives are outside its scope, although the standard may still be used for them if the supplier and the purchaser agree. It quotes GB/T 9445, JB/T 10061 and JB/T 10062, and is classified under J32 in the Chinese system and 77.140.85 internationally. It replaces JB/T 9020-1999.
