19、ong, 13/06/2009 08:09, Uncontrolled Copy, (c) BSI BS EN ISO 6974-6:2008 iv 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 t
20、echnical committees. Each member body interested 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 clos
21、ely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draf
22、t International Standards adopted by the technical 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 part
23、of ISO 6974 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 6974-6 was prepared by Technical Committee ISO/TC 193, Natural gas, Subcommittee SC 1, Analysis of natural gas. This first edition of ISO 6974-6, together with ISO 69
24、74-1, ISO 6974-2, ISO 6974-3, ISO 6974-4 and ISO 6974-5, cancels and replaces ISO 6974:1984 which specified only one method.
