In determination of liquid chemical products’ movement viscosity, the main include temperature, flow time and viscometer capillary constant. Moreover, viscometer tilt and amount of sample have influence on determination of kinematic viscosity. The accurate measurement result can be obtained if the five influencing factors are strictly controlled.%液体化工产品运动粘度测试中，除了主要影响因素温度、流动时间和粘度计毛细管常数之外，测定过程中粘度计倾斜和样品量对试样运动粘度的影响也比较重要，从这五个方面严格控制可得到较为准确的测定结果。
