ISO 13579-1:2013规定了一种测量能量平衡和计算过程效率的通用方法，该过程涉及工业炉子和炉子制造商设计的相关加工设备。该通用方法包括测量方法、计算（通用计算）和能量平衡评估报告。ISO 13579-1:2013不适用于工业炉和相关加工设备之外与工艺本身有关的任何效率。

ISO 13579-1:2013 specifies a general methodology for measuring energy balance and calculating the efficiency of the process involving industrial furnaces and associated processing equipment as designed by furnace manufacturers. This general methodology includes measurement methods, calculations (general calculation) and an energy balance evaluation report. ISO 13579-1:2013 is not applicable to any efficiencies related to the process itself outside of industrial furnaces and associated processing equipment.
