  • SF6 Handling Procedures

    Some SF6 properties from ASTM Standard Specification for Sulfur Hexafluoride, D 2472 – 81, are shown in the table below. SF6 is one of the heaviest known gases with a density about 5 times the density of air under similar conditions. SF6 shows little change in vapor pressure over a wide temperature range and is a soft gas in that
