JB/T 50171-1999 This standard is a revision of ZB J01 021-88 "Energy Consumption Classification of Ceramic Abrasives Firing Kilns". This standard specifies the energy consumption levels of tunnel kilns, down-flame kilns and ordinary trolley-type (drawer) kilns for firing ceramic grinding wheels and ceramic oilstones. Ceramic abrasive firing kilns are divided into first-class, second-class and third-class according to the comparable unit consumption of their furnace seats. If the comparable unit consumption of the furnace base does not reach the third-class index, it is outside the first-class category. This standard was first published on March 5, 1988.
