The standard GB/T 1660-2008 Determination of the kinematic viscosity of plasticizers specifies two methods for measuring the kinematic viscosity of plasticizers. Method A is suitable for liquid plasticizers with a kinematic viscosity of 1 centipoise to 15,000 centipoise. For samples over 15,000 centipoise, a Pinnacle Viscosity meter with a diameter of 5.0 mm or 6.0 mm needs to be used for determination. Rule B is specific to liquid plasticizers with a kinematic viscosity below 10,000 centipoise. The standard refers to a variety of relevant test methods, including the determination of kinematic viscosity of petroleum products and the determination of Enn's viscosity. It provides detailed definitions of terms and technical conditions, ensuring accurate measurement of the kinematic viscosity of plasticizers.
