ASTM E534

Chemical Analysis of Sodium Chloride

Applicability: ASTM E534 is a standard test method for the chemical analysis of sodium chloride, used to determine its purity and identify impurities like calcium and magnesium. It is applicable to a wide range of uses for sodium chloride, including road salt, laboratory reagents, and industrial applications where high purity is needed, such as the production of sodium compounds. It is also used as a referee method in the salt industry to ensure products meet specific quality and purity requirements.

Purpose: The purpose of ASTM E534 is to provide standard test methods for the chemical analysis of sodium chloride (table salt) to ensure its purity and suitability for various applications, such as road de-icing and use in chemical manufacturing. It outlines specific procedures for determining key properties like moisture content, water insolubles, and levels of calcium and magnesium.
