(Test Method)Standard Test Methods for Chemical Analysis of Sodium Chloride
Standard Test Methods for Chemical Analysis of Sodium Chloride
SIGNIFICANCE AND USE
3.1 Sodium chloride occurs in nature. It is a necessary article of diet as well as the source for production of many sodium compounds and chlorine. The methods listed in 1.2 provide procedures for analyzing sodium chloride to determine if it is suitable for its intended use.
SCOPE
1.1 These test methods cover the chemical analyses usually required for sodium chloride.
1.2 The analytical procedures appear in the following sections:

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.5 Review the current material safety data sheets (MSDS) for detailed information concerning toxicity, first-aid procedures, handling, and safety precautions.
