1.1 ,This practice covers a general guide for the ampulization and storage of gasoline and related hydrocarbon mixtures that are to be used as calibration standards or reference materials. This practice addresses materials, solutions, or mixtures, which may contain volatile components. This practice is not intended to address the ampulization of highly viscous liquids, materials that are solid at room temperature, or materials that have high percentages of dissolved gases that cannot be handled under reasonable cooling temperatures and at normal atmospheric pressure without losses of these volatile components.
