17、iv I SO 4002 All irthgs ersedevr Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inte
18、rested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnica
19、l Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the t
20、echnical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. I
21、SO shall not be held responsible for identifying any or all such patent rights. ISO 16664 was prepared by Technical Committee ISO/TC 158, Analysis of gases.

22、I SO 4002 All irthgs ersedevr v Introduction This International Standard uses the terms “calibration gas” for both gas mixtures and pure gases as the limiting case of gas mixtures. The quality of calibration gases in cylinders as certified by producers is defined by a) the correct analyte content; b
23、) a known uncertainty which is appropriate for its intended use; c) the stability; d) the homogeneity. During its utilization period, the quality of calibration gases is influenced by storage conditions at the manufacturers and users sites; transport conditions; modes of calibration gas withdrawal a
24、nd transfer; the transfer system employed.
