| BSI | 2013 | 82 |
IEC 62271-4:2013 applies to the procedures for handling of SF 6 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a) the description of the potential effects on health of SF 6 by products (former Annex D of IEC/TR 62271-303:2008) has been replaced by the calculation methods for evaluating of the potential effects on health of SF 6 by products (see Annex H); b) information about cryogenic reclaim of SF 6. Have been added (see Annex I); c) handling procedures for the most popular SF 6 mixtures have been added (see Annex J).
