ASTM E200-16

Standard Practice for Preparation, Standardization, and Storage of Standard and Reagent Solutions for Chemical Analysis

SIGNIFICANCE AND USE
4.1 The accuracy of many analytical measurements is dependent upon the manner in which the standard solutions are prepared and stored, and the accuracy with which they are standardized. Combining the methods recommended for the preparation and handling of such solutions into one practice eliminates the necessity for covering such details in all of the methods wherein the solutions are used.
SCOPE
1.1 This practice covers procedures for the preparation, standardization, and storage of the standard volumetric solutions and reagent testing solutions commonly used in chemical analysis.
