ASTM D 1827 Document Information:
Title
Standard Test Method for Gas Content (Nonacidic) of Insulating Liquids by Displacement with Carbon Dioxide
ASTM International
Publication Date:
Aug 15, 1992
Scope:
This test method describes the determination of the gas content of
electrical insulating liquids
with a viscosity of 216 cSt or less at 100°C. Any gas that is
nonreactive with a strong caustic
solution may be determined.
NOTE 1 - The test method has a bias for samples containing gases other
than oxygen and nitrogen in
atmospheric ratios due to differential solubility effects. Gases which
react with KOH such as
carbon dioxide will not be measured. Unsaturated hydrocarbons such as
acetylene, if present, will
react with KOH to a small degree and will result in an underestimation
of the total gas present.
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.
Keywords:
- carbon dioxide
- dissolved gases
