GB/T 2895-2008 specifies the determination method of partial acid value and total acid value of plastic polyester resin. The standard clarifies the determination principle, standardizes the preparation process of instruments and equipment, reagent materials and samples, elaborates the operation steps such as titration, and gives the result calculation method and precision requirements. It provides a unified technical specification for the accurate determination of polyester resin acid value, which helps to evaluate Resin performance, control product mass and guide production process optimization.
