ASTM D6806-02(2017)

Standard Practice for Analysis of Halogenated Organic Solvents and Their Admixtures by Gas Chromatography

ABSTRACT
This practice covers the standard procedure for determining impurities, stabilizers, and assays of halogenated organic solvents and their admixtures by gas chromatography. It is not the intent of this practice to provide a specific method of gas chromatography, but rather it defines what is required for a user to demonstrate that a method to be used is valid. The use of this practice allows the user to use the most effective technology and demonstrate that the method in use complies with a standard practice and is valid for the analytes involved.
SCOPE
1.1 This practice covers the determination of impurities, stabilizers and assay of halogenated organic solvents and their admixtures by gas chromatography.  
1.2 It is not the intent of this practice to provide a specific method of gas chromatography. The intent of this practice is to define what is required for a user to demonstrate that a method to be used is valid. The reason for this approach, as opposed to stating a method, is that gas chromatography is such a dynamic field that methods are often obsolete by the time they are validated. The use of this practice allows the user to use most effective technology and demonstrate that the method in use complies with a standard practice and is valid for the analysis of halogenated organic solvents and their admixtures.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
