本标准规定了用高效液相色谱法测定含脂肪酸甲酯(FAME)体积分数小于5%的柴油和馏程在150℃~400℃的石油馏分中单环芳烃、双环芳烃和三环+ 芳烃含量的方法。多环芳烃含量由双环芳烃和三环+ 芳烃含量加和求得,总芳烃含量由单环芳烃、双环芳烃和三环+ 芳烃含量加和求得。
本标准适用于测定含脂肪酸甲酯(FAME)体积分数小于5%的柴油和馏程在150℃~400 ℃的石油馏分中单环芳烃、双环芳烃和三环+ 芳烃含量。在试样单环芳烃含量(质量分数)为6%~30%,双环芳烃含量(质量分数)为1%~10%,三环+ 芳烃含量(质量分数)为0~2%,多环芳烃含量(质量分数)为1%~12%,总芳烃含量(质量分数)为7%~42%的范围,进行了方法精密度确定。试样中含有硫、氮和氧的化合物可能对测定结果有影响。单烯烃对测定结果无影响,但是共轭二烯烃和共轭多烯烃,可能对测定结果有影响。
