| Summary: | IEC 60480:2019 provides criteria for the re-use of sulphur hexafluoride (SF 6) and its mixtures after recovery and reclaiming from electrical equipment (e.g. for maintenance, at the end-of-life). Sulphur hexafluoride (SF 6), nitrogen (N 2) and carbon tetrafluoride (CF 4), are gases commonly used for electrical equipment. Taking into account environmental concerns, particular attention is paid to re-use criteria for SF 6 and its mixtures with N 2 and CF 4 for its use in electrical equipment. Procedures for recovering and reclaiming used SF 6 and its mixtures are outside the scope of this document and are described in IEC 62271-4. This document provides several annexes on the description of the different methods of analysis, on by-products, on the procedure for evaluating the potential health effects from by-products, on cryogenic reclaiming of SF 6, and on reclaiming recommendations. Storage, transportation and disposal of SF 6 and its mixtures are outside the scope of this document and are covered by IEC 62271-4. Procedures to determine SF6 leakages are described in IEC 60068-2-17. For the purposes of this document, the complementary gases used in SF 6 mixtures will be limited to N 2 or CF 4. This third edition cancels and replaces the second edition, published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: • specifications for the re-use of SF 6 have been confirmed; • specifications for the re-use of SF 6 mixtures, namely SF 6/N 2 and SF 6/CF 4 mixtures are included; • as a result of a new repartition of annexes in IEC 60376, IEC 60480 and IEC 62271-4, this new edition now contains the following five annexes: – Annex A: Description of methods of analysis (on-site and laboratory); – Annex B: By–products of SF 6 and its mixtures; – Annex C: Procedure for evaluating the potential effects on health from by products of SF 6 and its mixtures; – Annex D: Reclaiming recommendations. – Annex E: Cryogenic reclaiming of SF 6; |
