ActiveBlack petroleum products--Determination of kinematic viscosity (reverse-flow method) and calculation of dynamic viscosity
深色石油产品运动粘度测定法 (逆流法) 和动力粘度计算法
Application Summary AI generated
This standard specifies the reverse-flow method for determining the kinematic viscosity of black petroleum products, such as heavy fuel oils and crude residues, which are too opaque for conventional viscometers. It is applied in petroleum testing laboratories and quality control settings to measure viscosity at a controlled temperature, and it also provides the calculation for dynamic viscosity from the measured kinematic viscosity and density.
