IEC 60480:2019提供了六氟化硫（SF6）及其混合物在从电气设备中回收和再利用后的再利用标准（例如，在报废时用于维护）。 六氟化硫(SF6)、氮气(N2)和四氟化碳(CF4)是通常用于电气设备的气体。考虑到环境问题，特别关注SF6及其与N2和CF4的混合物在电气设备中的再利用标准。回收和再利用使用过的SF6及其混合物的程序超出了本文件的范围，并在IEC 62271-4中进行了描述。 本文件提供了几个附件，描述了不同的分析方法、副产品、评估副产品对健康的潜在影响的程序。产品，SF6的低温回收，以及回收建议。 SF6及其混合物的储存、运输和处置超出了本文件的范围，由IEC 62271-4涵盖。IEC 60068-2-17中描述了确定SF6泄漏的程序。 出于本文件的目的，SF6混合物中使用的补充气体将限于N2或CF4。 第三版取消并取代了2004年出版的第二版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: ？SF6的再利用规范已得到确认； ？包括SF6混合物，即SF6/N2和SF6/CF4混合物的再利用规范； ？由于IEC 60376、IEC 60480和IEC 62271中附件的新重新划分-4、本新版现包含以下五个附件: -附件A:分析方法说明（现场和实验室）； -附件B:SF6及其混合物的副产品； -附件C:评估SF6及其混合物副产品对健康的潜在影响的程序； -附件D:回收建议。 -附件E:SF6的低温回收

IEC 60480:2019 provides criteria for the re-use of sulphur hexafluoride (SF₆) and its mixtures after recovery and reclaiming from electrical equipment (e.g. for maintenance, at the end-of-life).
Sulphur hexafluoride (SF₆), nitrogen (N₂) and carbon tetrafluoride (CF₄), are gases commonly used for electrical equipment. Taking into account environmental concerns, particular attention is paid to re-use criteria for SF₆ and its mixtures with N₂ and CF₄ for its use in electrical equipment. Procedures for recovering and reclaiming used SF₆ 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 SF₆, and on reclaiming recommendations.
Storage, transportation and disposal of SF₆ 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 SF₆ mixtures will be limited to N₂ or CF₄.
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 SF₆ have been confirmed;
？ specifications for the re-use of SF₆ mixtures, namely SF₆/N₂ and SF₆/CF₄ 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 SF₆ and its mixtures;
– Annex C: Procedure for evaluating the potential effects on health from by products of SF₆ and its mixtures;
– Annex D: Reclaiming recommendations.
– Annex E: Cryogenic reclaiming of SF₆
