SF6 Mixtures. In addition to the use of sulphur hexafluoride (SF 6) as a single gas, mixtures of SF 6 with nitrogen (N 2) or tetrafluoromethane (CF 4) are also used as insulating or test gas.. The IEC recommends a purity of SF 6 of at least 99.7 vol.-% for the use in mixtures. SF 6 gas reconditioned or treated by DILO clearly meets these criteria and is therefore suitable for the use in gas ...Sulfur hexafluoride - Wikipedia
