DANSK DSF/FPREN 60376 [ Draft ]

This International Standard defines the quality for technical grade Sulphur hexafluoride (SF6) and complementary gases such as nitrogen (N2) and carbon tetra-fluoride (CF4), for use in electrical equipment. The provenance of the above gases – unless taken from electrical equipment for its reuse which is covered by IEC60480 – is of no consequence provided the gas is commercially available and equals or exceeds the quality expectations defined in this international standard. Analytical techniques, covering both laboratory and in-situ portable instrumentation, applicable to the analysis of SF6, N2 and CF4 gases prior to the introduction of these gases into the electrical equipment are also described in this standard. This standard provides some information on Sulphur hexafluoride in Annex A and on Environmental effects of SF6 in Annex B. Information about SF6 by-products, procedure for evaluating the potential effects on health of SF6 by-products are covered by IEC 60480 Guidelines for the checking and treatment of sulphur hexafluoride (SF6) taken from electrical equipment and specification for its re-use The handling and disposal of these items should be carried out according to international and local regulations with regard to the impact on the environment. Handling of SF6 and its mixtures is covered by IEC 62271-4.
