This standard specifies methods for determining polymer dispersion density using the Specific Gravity bottle method and the specific gravity meter method. The Specific Gravity bottle method is suitable for polymer dispersion in all viscosity ranges, and the density is determined by the Specific Gravity bottle calibrating and weighing. The specific gravity meter method is suitable for polymer dispersion of medium and high viscosity, and the sample density is read by the specific gravity meter. The standard provides specific operation steps and instrumental requirements for accurate determination of polymer dispersion density, which helps to ensure product conformity and quality control.
