ActiveStandard test method for measurement of low-temperature viscosity of lubricants―Brookfield viscometer method
润滑剂低温黏度的测定 勃罗克费尔特黏度计法
Application Summary AI generated
This standard specifies a test method using a Brookfield viscometer to measure the low-temperature viscosity of lubricants, including engine oils, gear oils, and hydraulic fluids. It is applied in the petroleum industry for quality control and product development, particularly to evaluate the cold-flow performance and pumpability of lubricants in automotive and industrial equipment operating in cold climates. The method is critical for ensuring that lubricants maintain adequate fluidity at low temperatures to prevent equipment startup failures and wear.
