1799-2005 "Petroleum products.calculation of viscosity index from kinematic viscosity"

The TIS 1799-2005 standard specifies the method of calculating the viscosity index for the kinematic viscosity of petroleum products. The standard applies to lubricating oils and Miscellaneous related petroleum products and aims to calculate the viscosity index by measuring their kinematic viscosity at 40 ° C and 100 ° C. The viscosity index is a characteristic index that characterizes the viscosity of petroleum products as a function of temperature. The higher the value, the smaller the viscosity change of the product at different temperatures. The standard describes the calculation method and steps in detail, ensuring the accuracy and conformity of the test results. It provides an important basis for the quality control and performance evaluation of petroleum products.
