GB/T 8297-2023 specifies the determination method of potassium hydroxide (KOH) value for condensed natural latex. The standard specifies the equipment required for the test, such as Burette, conicalflask, etc., and details the reagent preparation process. Sample Handling and titration operations have strict specifications, from latex measurement and diluting, to the speed control and end point judgment of the titration process. By measuring the KOH value, the free fatty acid content in the latex can be evaluated, providing key data for the mass control of condensed natural latex, helping relevant manufacturers to ensure product performance and meet the needs of Rubber processing and other industries.
