This standard uses the International Juice Union IFJU analytical method and the international standard ISO1842-1975, which specifies the principle of measuring the pH value of the solution, the required instruments such as pH Meter, Glass electrode and Calomel electrode, and the required reagents such as pH3.57, pH6.88, pH4.00 and pH5.00 buffer solution preparation method. The determination procedure includes the correction and determination steps of the pH Meter, in which the solution to be tested is shaken several times and a stable measurement value is ensured.
