JB/T 50153-1999 This standard is a revision of ZB J01 003-87 "Energy Consumption Classification of Forging Heating Furnaces". This standard specifies the energy consumption levels of flame furnaces used for forging heating in machinery industry enterprises. Forging heating furnaces are divided into special, first-class, second-class and third-class according to the comparable unit energy consumption per ton of qualified forgings. 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.
