ASTM D2472 : 00(2006)

Standard Specification for Sulfur Hexafluoride

Standard Details

1.1 This specification applies to sulfur hexafluoride for use as an electrical insulating gas.

Note 1—This specification is intended to apply only to gas as purchased. However, the test methods referred to in this standard may be useful in the evaluation of in-service or used gas. Test Method D 2284 may be particularly helpful since many sulfur hexafluoride decomposition products are acidic. Test Method D 2284 should not be used to evaluate the total amount of sulfur hexafluoride decomposition nor to identify contaminant species. This can only be done by gas chromatography and similar instrumental techniques.

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.
