摘要
采用自动量热仪对燃料油进行热值测定,针对现行国家标准中错误和滞后的内容,简化了检测步骤。经对标准样品进行测试,精密度5次实验结果的相对标准差不大于0.2%,准确度为实验结果平均值与标准热值相差不大于50J/g。两次样品测定结果的绝对差值不大于120J/g,均能达到现行国家标准GB/T384-1981和美国标准ASTMD240-02的要求。
The heat of combustion of fuel oil was determined by auto-calorimeter, the incorrect and outdated descriptions in the national standard were modified and the testing procedures were simplified. The result obtained by standard sample, RSD was calculated to be no more than 0.2% by 5 measurements, the discrepancy in accuracy test between mean value of test results and reference＇value was no more than 50J/g. The absolute discrepancy of two tests was no more than 120J/g and meets the requirements of GB/T 384-1981 and ASTM D240-02.
