3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 gas content of oil by volume - in Method A, the total volume of gases, corrected to 760 torr (101.325 kPa) and 0°C, contained in a given volume of oil, expressed as a percentage.In Methods B and C, the sum of the individual gas concentrations corrected to 760 torr (101.325 kPa) and 0°C, expressed in percent or parts per million.
3.1.2 headspace - a volume of gas phase in contact with a volume of oil in a closed vessel. The vessel is a headspace vial of 20-mL nominal capacity.
3.1.2.1 Discussion - Other vessel volumes may also be used, but the analytical performance may be somewhat different than that specified in Method C.
3.1.3 parts per million (ppm) by volume of (specific gas) in oil - the volume of that gas corrected to 760 torr (101.325 kPa)and 0°C, contained in 10/*6 volume of oil.
3.1.4 sparging, v - agitating the liquid sample using a gas to strip other gases free.
3.1.5 volume concentration of (specific gas) in the gas sample - the volume of the specific gas contained in a givenvolume of the gas sample at the same temperature and pressure (as the measured total volume), expressed either as a percentage or in parts per million.
