JB/T 50154-1999 This standard is a revision of ZB J01 004-87 "Energy Consumption Classification of Heat Treatment Furnaces". This standard specifies the flame energy consumption levels for the first heat treatment of forgings and the heat treatment of forgings in machinery industry enterprises. Various heat treatment furnaces are divided into special, first-class, second-class and third-class according to comparable unit energy consumption. Comparable unit energy consumption that does not reach the third-class index is classified as out-of-class. This standard was first published in 1987.
