DIN EN 62271-4:2014-06

This part of IEC 62271 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. These procedures are regarded as minimum requirements to ensure the safety of personnel working with SF₆ (see Annex B) and to minimize the SF₆ emission to the environment. This standard generally applies also to gas mixtures containing SF₆. The particularities for their handling are covered in Annex J. With respect to DIN V 62271-303 (VDE V 0671-303):2010-06 the following technical changes have been made: - The description of the potential effects on health of SF₆ by-products (former Annex D of CLC/TR 62271-303:2009) has been replaced by the calculation methods for evaluating of the potential effects on health of SF₆ by-products (see Annex H). - Information about cryogenic reclaim of SF₆ has been added (see Annex I). - Handling procedures for the most popular SF₆ mixture gases have been added (see Annex J). The responsible body is DKE/UK 432.1 "Hochspannungs-Schaltgeräte" ("High-voltage switchgear and controlgear") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
