IEC 60480:2019 provides criteria for the re-use of sulphur hexafluoride (SF 6<\/sub>) and its mixtures after recovery and reclaiming from electrical equipment (e.g. for maintenance, at the end-of-life). Sulphur hexafluoride (SF 6<\/sub>), nitrogen (N 2<\/sub>) and carbon tetrafluoride (CF 4<\/sub>), are gases commonly used for electrical equipment. Taking into account environmental concerns, particular attention is paid to re-use criteria for SF 6<\/sub> and its mixtures with N 2<\/sub> and CF 4<\/sub> for its use in electrical equipment. Procedures for recovering and reclaiming used SF 6<\/sub> 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<\/sub>, and on reclaiming recommendations. Storage, transportation and disposal of SF 6<\/sub> 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<\/sub> mixtures will be limited to N 2<\/sub> or CF 4<\/sub>. 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: \u2022 specifications for the re-use of SF 6<\/sub> have been confirmed; \u2022 specifications for the re-use of SF 6<\/sub> mixtures, namely SF 6<\/sub>\/N 2<\/sub> and SF 6<\/sub>\/CF 4<\/sub> mixtures are included; \u2022 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: \u2013 Annex A: Description of methods of analysis (on-site and laboratory); \u2013 Annex B: By\u2013products of SF 6<\/sub> and its mixtures; \u2013 Annex C: Procedure for evaluating the potential effects on health from by products of SF 6<\/sub> and its mixtures; \u2013 Annex D: Reclaiming recommendations. \u2013 Annex E: Cryogenic reclaiming of SF 6<\/sub>;<\/p>\n
