IEC 60480:2019 PDF (Not Available)

IEC 60480:2019 is a standard that provides specifications for the re-use of sulphur hexafluoride (SF₆) and its mixtures in electrical equipment. The standard focuses on the recovery and reclaiming of SF₆and its mixtures after they have been used in electrical equipment, such as during maintenance or at the end of their life cycle.

The standard covers the criteria for re-use of SF₆and its mixtures with nitrogen (N₂) and carbon tetrafluoride (CF₄), taking into account environmental concerns. It does not include procedures for recovering and reclaiming used SF₆and its mixtures, as those are described in a separate standard.

IEC 60480:2019 includes several annexes that provide additional information, such as the methods of analysis for SF₆and its mixtures, the by-products of SF₆, the evaluation of potential health effects from these by-products, recommendations for cryogenic reclaiming of SF₆, and general recommendations for reclaiming.

The standard does not cover the storage, transportation, and disposal of SF₆and its mixtures, as those are addressed in a different standard. Procedures for determining SF₆leakages are described in yet another standard.

This third edition of the standard cancels and replaces the previous edition from 2004. The current edition includes significant technical changes, such as the confirmation of specifications for SF₆re-use, the inclusion of specifications for SF₆mixtures (SF₆/N₂and SF₆/CF₄), and the repartition of annexes from other related standards.
