Significance and Use

4.1 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.

4.2 The presence of free halogens in halogenated solvents is often an indication that the stabilizers in the solvent system are breaking down.

4.3 This test method provides a means of detecting the presence of free halogens in halogenated solvents and their admixtures.

Scope

1.1 This test method covers the evaluation of free halogens in halogenated organic solvents and their admixtures.
