    GB/T 6743-2008
    Plastics(polyester resins) and paints and varnishes(binders) - Determination of partial acid value and total acid value

    GB/T 6743-2008 "Plastics—Polyester resins and paints and varnishes binders—Determination of partial acid value and total acid value" specifies titration methods for determining two types of acid values, applicable to relevant resin and binder products. The sample is dissolved in ethanol or a mixed solvent and titrated with a standard potassium hydroxide solution to calculate the acid value result. The test requires instruments such as a burette, analytical balance, constant-temperature water bath, and conical flask, providing a standardized method for evaluating the chemical characteristics and usage compatibility of products.
