Standard Specification for Sulfur Hexafluoride
|Publication Date:||1 October 2015|
|ICS Code (Salts):||71.060.50|
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 D2284 may be particularly helpful since many sulfur hexafluoride decomposition products are acidic. Test Method D2284 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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.

This specification covers the requirements for sulfur hexafluoride intended for use as an electrical insulating gas. However, this specification applies only to gas as purchased. Tests for water content, acidity (hydrolyzable fluorides), noncondensable gas and carbon tetrafluoride content, and assay shall be performed and shall conform to the requirements specified.View Less
