1. Scope 1.1 This test method covers two procedures for extraction and measurement of gases dissolved in electrical insulating oil having a viscosity of 20 cSt (100 SUS) or less at 40°C (104°F), 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 8.1.8.
