GB/T 11137-1989 specifies the method for determining the kinematic viscosity of dark petroleum products (such as heavy fuel oil, residual oil, etc.) using a reverse-flow capillary viscometer, as well as the method for calculating dynamic viscosity. This method is specifically designed for opaque, high-viscosity oil products and serves as a supplement to the GB/T 265 method.
