The SF6 produced by Solvay Fluor GmbH is manufactured in a plant that ensures consistent quality with a purity of min. 99.993%.
It corresponds to the following guarantee-analysis which in turn conforms to IEC 376, 1st Edition, Section 3 or to IEC 376, Chapter 3 and to VDE 0373, Part 1, Chapter 3 (according to this standard all values apply to the composition of the liquid phase).
In general, the impurities in Solvay sulfur hexafluoride are substantially less than the maximum values specified in the guarantee-analysis.
The table below shows Solvay’s typical quality standards specification.
Prior to shipment, every batch of SF6 is tested for physiological safety (cf. Toxicity).
