A test method for halogenated hydrocarbons has been evaluated and information is provided for the user. Four compounds were investigated, carbon tetrachloride, ethylene dichloride, tetrachloroethylene, and trichloroethylene. The subject compounds remained stable in compressed gas mixtures in aluminum and steel cylinders for 4 months. In Tedlar bags held at ambient temperatures, carbon tetrachloride and tetrachloroethylene remained stable for 10 days, trichloroethylene for 2 days, and ethylene dichloride for one day. Heating causes decreases in stabilities. A procedure was developed to remove persistent residues from Tedlar bags that had contacted high concentrations of halogenated hydrocarbons. Information is also included on gas chromatographic columns for use in this method of analysis.
