Scope

This standard specifies a general method for the determination of non-condensable gases in the gas phase of fluoroalkanes - gas chromatography. This standard applies to the determination of non-condensable gases in the gas phase of medium-pressure, high-pressure and ultra-high pressure fluoroalkanes. The detection sensitivity of this standard test method is 0.02% (volume fraction).
