16、6, Uncontrolled Copy, (c) BSI 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 technical committees. Each member body inte
17、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
18、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
19、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
20、SO shall not be held responsible for identifying any or all such patent rights. ISO 7270 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Testing and analyses. This part of ISO 7270 cancels and replaces ISO 7270:1987, which has been technically revised. I
21、SO 7270 consists of the following parts, under the general title Rubber Analysis by pyrolytic gas- chromatographic methods: Part 1: Identification of polymers (single polymers and polymer blends) Part 2: Determination of styrene/butadiene/isoprene ratio At the time of publication of this part of ISO
22、 7270, Part 2 was in preparation.
