GB/T 11145-2014 specifies a method for determining the viscosity of lubricants (such as engine oils and gear oils) at low temperatures (e.g., -5°C to -40°C) using a Brookfield rotational viscometer. This method simulates cold-start conditions, and the measured low-temperature apparent viscosity is a key indicator for evaluating the low-temperature fluidity and startability of lubricants.
