1.1 These test methods cover the determination of the total volatile organic chlorides in concentrations from 10 to 100 ppm in butane-butene mixtures. The amperometric finish is not directly applicable in the presence of other substances that combine with silver ion or oxidize chloride ion in dilute acid solution. Bromides, sulfides, ammonia, tobacco smoke, and more than 25 181g of hydrogen peroxide in the test solution interfere in the spectrophotometric procedure.
1.2 Dissolved sodium chloride is not quantitatively determined using these test methods.
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. Specific precautionary statements are given in Sections 5, 8, 11, 14, 19, and Annex A1.
