GB/T 1730-2007 "Paints and Varnishes - Pendulum Damping Test" specifies a method for determining the hardness of paint films using a pendulum damping tester, applicable to assessing the hardness and deformation resistance of paint films for paints and varnishes. The hardness is characterized by the damping time of the pendulum swinging on the surface of the paint film, with longer damping times indicating higher film hardness. The test requires instruments such as a pendulum damping tester, a constant temperature and humidity chamber, and standard test panels, providing a standardized method for evaluating the physical properties of paint films.
