Standard Test Method for Free Halogens in Halogenated Organic Solvents and Their Admixtures
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the evaluation of free halogens in halogenated organic solvents and their admixtures.
1.2 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.
Significance and Use
Free halogens will react with any residual moisture in a solvent to form acid. These acids can cause corrosion to process and storage equipment used for halogenated solvents.
The presence of free halogens in halogenated solvents is often an indication that the stabilizers in the solvent system are breaking down.
This test method provides a means of detecting the presence of free halogens in halogenated solvents and their admixtures.
