    Abstract - (Show below) - (Hide below)

    Concerns the re-use of sulfur hexafluoride (SF6) after removal from electrical equipment (for maintenance, or at the end of life). This standard recommends procedures for reclaiming used SF6 and for restoring its quality to an acceptable level, which would allow the filling of new or existing electrical equipment. This standard provides guidance to operational and maintenance personnel for the testing and safe handling of used SF6 . The main changes with respect to the previous edition are listed below: - updating of standard as it relates to environmental issues, storage and analytical methods; - addition of specification for the re-use of gas; - inclusion of a regeneration process for sulfur hexafluoride taken from electrical equipment.
