PD CLC/TR 62271-303:2009  High-voltage switchgear and controlgear. Use and handling of sulfur hexafluoride (SF6) PD CLC/TR 62271-303 is a technical report which addresses the procedures for safe and environmental compatible handling of SF6 during installation, commissioning, normal and abnormal operations, disposal at the end-of-life of high-voltage switchgear and controlgear. Storage and transportation of SF6 are also covered. These procedures should be regarded as minimum requirements to ensure the safety of personnel working with SF6 and to minimize the SF6 emission to the environment. This technical report generally applies also to gas mixtures containing SF6.
