Scope

This part of GB/T 12008 specifies the method for determining the viscosity of polyether polyols.
Method A is the Brookfield viscosity method. This test method is suitable for determining the viscosity of polyether polyols with a viscosity range of (10 to 105) mPa·s at 25°C or 50°C. It is also suitable for determining the viscosity of more viscous samples that can be dissolved in n-butyl acetate.
Method B is the rotational viscosity method. This test method is suitable for determining the viscosity of polyether polyols with a viscosity range of (10 to 106) mPa·s at 25°C.
