This standard is equivalent to international standard ISO 3696 (1987) Water for Analytical Laboratory Use - Specification and Test Methods 1. Subject and the Aspect(s) Covered This standard regulates classes, specifications and test method of water for analytical laboratory use. This standard is applicable to water for test use of chemical analysis and inorganic trace analysis. Water of different classes can be adopted according to practical conditions. 2. Normative Reference GB/T601-1988 Chemical Reagent - Preparations of Standard Volumetric Solutions GB 602 Chemical Reagent - Preparations of Standard Solutions for Impurity GB/T 603-2002 Chemical Reagent - Preparations of Reagent Solutions for Use in Test Methods GB 9724 Chemical Reagent - General Rules for the Determination of pH GB 9740 Chemical Reagent - General Method for the Determination of Dry Residue after Evaporation 3. Appearance Water for analytical laboratory use shall be colorless transparent liquid through visual observation. 4. Classes Raw water for analytical laboratory use shall be drinking water or water with appropriate purity. Water for analytical laboratory use is classified into three classes: class-I water, class-II water and class-III water.
