GB/T 266-1988 specifies the test method for determining the Engler viscosity of petroleum products using an Engler viscometer. Engler viscosity is a conditional viscosity, expressed as the ratio of the time required for a sample to flow out 200 milliliters from the Engler viscometer at a certain temperature to the time required for the same volume of distilled water to flow out at 20°C (i.e., the "water value").
