GB 6853-1986 focuses on the pH reference reagent potassium dihydrogen phosphoric acid. The standard specifies its technical requirements, including key indicators such as purity and pH value, specifies inspection rules in detail, covers sampling methods and judgment criteria, and also provides test methods for the determination of various indicators. As an important pH reference reagent, potassium dihydrogen phosphoric acid is produced and inspected according to this standard, which can ensure the accuracy of its acidity measurement, calibrated pH Meter, etc., providing a reliable pH measurement basis for chemical analysis, scientific research and other fields, and assisting the accurate development of related experiments and tests.
