This standard specifies a general method for the determination of acid alkalinity in pigment water extracts, applicable to all pigments and extenders. Tests are performed using analytically pure reagents including muriatic acid, sodiumhydrate or potassium hydroxide and titrated with a methyl red indicator. The standard provides precise instrumentation requirements such as Burette and pH measurement devices to ensure the accuracy of acid alkalinity determination. If the standard method is not applicable to a specific product, special methods can be developed as needed.
