Scope
This standard specifies a general method for determining non-condensable gases in fluorinated alkane gas phases—gas chromatography.
This standard is applicable to the determination of non-condensable gases in medium-pressure, high-pressure, and ultra-high-pressure fluorinated alkane gas phases. The detection sensitivity of the test method in this standard is 0.02% (by volume fraction).
