Abstract：The uncertain factors influencing the oil content of microcrystalline wax were analyzed and evaluated. The synthetic uncertainty was evaluated by calculating uncertainly factors include the repetitive detections, weight of oil residue, weight of wax sample, volume of solvent, volume of solvent evaporated. The experimental results showed that the sources of uncertainty were mainly derived from the repetitive detections, the second was the volume of solvent and weight of oil residue. Through the evaluation of the uncertainty, it can improve the reliability of the test results and provide theoretical basis for the accurate determination of the oil content of microcrystalline wax.
