摘要：This document specifies a method for the determination of the gross heat of combustion (QPCS) of products at constant volume in a bomb calorimeter. This method is intended to be applied to solid products. NOTE Liquids can be tested with similar equipment and using conditions described in ASTM D240, as described in IEC 61039 using ISO 1928 test equipment. Annex A specifies the calculation of the net heat of combustion, QPCI, when required. Information on the precision of the test method is given in Annex B.
