This International Standard specifies a manometric method for the preparation of calibration gas mixtures for which the accuracy of the concentration of each component may vary within very wide limits, depending on the mixtures being prepared. For example, a relative accuracy of 1%, on a concentration expressed in pressure ratio or mole fraction, may be obtained in the case mixtures of gases which approach ideal gases, but with certain gases, such as hydrocarbons or polar compounds for example, the potential errors may be very much greater.
