Additional information

1. Scope

1.1 This test method covers three procedures for extraction and measurement of gases dissolved in electrical insulating oil having a viscosity of 20 cSt (100 SUS) or less at 40^oC (104^oF), and the identification and determination of the individual component gases extracted. Other methods have been used to perform this analysis.

1.2 The individual component gases that may be identified and determined include:

	Hydrogen-H₂
	Oxygen-O₂
	Nitrogen-N₂
	Carbon monoxide-CO
	Carbon dioxide-CO₂
	Methane-CH₄
	Ethane-C₂H₆
	Ethylene-C₂H₄
	Acetylene-C₂H₂
	Propane-C₃H₈
	Propylene-C₃H₆

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. For specific precautionary statements see 6.1.8.
