4. Summary of Test Method
4.1 A liquid specimen is injected into a combustion tube
maintained at 900°C having a flowing stream of oxygen and
argon carrier gas. Oxidative pyrolysis converts the organic
halides to hydrogen halides that then flow into a titration cell
where it reacts with silver ions present in the electrolyte. The
silver ion thus consumed is coulometrically replaced and the
total electrical work to replace it is a measure of the organic
halides in the specimen injected (see Annex A1).
