ASTM D7213

ASTM D7213 is a standard test method developed by ASTM International (formerly known as the American Society for Testing and Materials) for the determination of the low-temperature, low-shear rate viscosities of lubricants using tapered, rotational viscometers. This test method is specifically designed to measure the viscosity of lubricating oils and is commonly used in the petroleum and automotive industries to assess the performance of lubricants at low temperatures.

In this test, a sample of the lubricant is subjected to controlled shear rates and temperatures in a viscometer, and the resulting viscosity measurements are used to evaluate the flow behavior of the lubricant under low-temperature conditions. This information is important for assessing the suitability of a lubricant for use in cold environments, such as those encountered in winter or in certain industrial applications.
