Title High-voltage switchgear and controlgear - Part 4: Handling procedures for sulphur hexafluoride (SF6) and its mixtures
Project Number 24139
Abstract/Scope IEC 62271-4:2013 applies to the procedures for handling of SF6 during installation, commissioning, normal and abnormal operations, disposal at the end of life of high voltage switchgear and controlgear. This first edition cancels and replaces the first edition of IEC/TR 62271-303 published in 2008. This first edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the description of the potential effects on health of SF6 by products (former Annex D of IEC/TR 62271-303:2008) has been replaced by the calculation methods for evaluating of the potential effects on health of SF6 by products (see Annex H); b) information about cryogenic reclaim of SF6. Have been added (see Annex I); c) handling procedures for the most popular SF6 mixtures have been added (see Annex J).
