1 Scope
This Part specifies the method for determination of moisture in gases by determination of dew point.
This Part is applicable to the determination of moisture in hydrogen, oxygen, nitrogen, helium, neon, argon, krypton, xenon, nitrous oxide, sulphur hexafluoride, etc., as well as mixture gas of such gases. This Part is not applicable to the gases which are condensate before moisture condensation , and which may react with moisture.
This Part is applicable to the determination of gas dew point within 0 ℃ to -120 ℃.
