Description: nominal plane specified by a measurement standard to ensure comparability of results; Name: reference level
Description: horizontal plane for use as the datum for height measurement; Name: Reference plane
Description: minimum value of ratio between the applied shear stress and rate of shear of a liquid at concept temperature it is sometimes referred to as the coefficient of dynamic viscosity, or simply viscosity. Thus dynamic viscosity is a measure of the resistance to flow or deformation of a liquid; Name: minimum dynamic viscosity at design temperature
