This standard specifies two methods for determining the partial acid value and total acid value of polyester resins, used to assess the content of acidic components in the resin. The partial acid value primarily measures acidic substances that can be extracted by a specific solvent, while the total acid value reflects all acidic components in the resin. According to this standard, the determination typically requires a fully automatic potentiometric titrator with potentiometric titration functionality, equipped with specific measurement electrodes, titration devices, and analysis software, enabling the automation of the titration process and precise calculation of results.
