Determinating quality control/assurance index of petroleum in water by infrared spectrometry was achieved based on a large number of monitoring data from 79 laboratories in 9 provinces.The study shows that when the standard sample concentration is in the range of 20-70 mg·L^-1,the RSD（relative standard deviation in the control room）≤5.0%,and the RSD＇（relative standard deviation between laboratories）≤5.0%;the repeatability was between 0.7 mg·L^-1 and 1.7 mg·L^-1,and the reproducibility was between 1.2 mg·L^-1 and 7.3 mg·L^-1;RD（the relative deviation of the controlled actual sample）≤20.0% when the sample concentration was below 1.0 mg·L^-1;RE（the relative error） was controlled within ±7.0% when the sample concentration was between 20-70 mg·L^-1;the recovery rate with added specimen was between 80%-120%.
