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.
1.1 This test method covers the evaluation of free halogens in halogenated organic solvents and their admixtures.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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 and health practices and determine the applicability of regulatory limitations prior to use.
