Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method covers the determination of the acidic fluorides of sulfur hexafluoride (SF6).
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Significance and Use
Acidic fluorides are undesirable in SF6 used as an electrical insulating gas in that they may contribute to corrosion or constitute dielectric hazard.
This test method is valid for both new and used SF6. In used SF6, it will only measure those active species which are hydrolyzable.
