17、n) 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 interested in a subject for which a technical committee has been established has the right to be rep
18、resented 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 Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards a
19、re 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internatio
20、nal 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 International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. IS
21、O 14897 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 12, Thermosetting materials. This second edition cancels and replaces the first edition (ISO 14897:2000), which has been technically revised. The principal technical change is the incorporation of significantly improved
22、 precision data. The standard is based on ASTM D 4672, Standard Test Methods for Polyurethane Raw Materials Determination of Water Content of Polyols. iv BS ISO 14897:2002 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 27 08:11:49 GMT+00:00 2006, Uncontrolled Copy, (c) BSI INTENRATIONAL TSANDAD
