JB/T 50175-1999 This standard is a revision of ZB J01 025-88 "Energy Consumption Classification of Electric Carbon Roasting Kilns and Graphitization Furnaces". This standard specifies the energy consumption levels of electric carbon roasting kilns and graphitization furnaces. This standard applies to electric carbon products, carbon rod product roasting kilns and electric carbon product intermittent graphitization furnaces. Various furnaces are classified into special, first-class, second-class and third-class according to the average energy consumption per unit of qualified products during the statistical period. Those whose average energy consumption does not reach the third-class index are classified as out-of-class. This standard was first published on November 13, 1988.
