Standard Test Method for Chloride in Trichlorotrifluoroethane
SIGNIFICANCE AND USE
3.1 This test method determines ionizable chloride that can be aqueously extracted from trichlorotrifluoroethane.
3.2 This test method can be used to establish production and purchasing specifications.
SCOPE
1.1 This test method covers the determination of chloride in trichlorotrifluoroethane and other halocarbons that are liquid at room temperature.
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.
