13、004(E) iv ISO 2004 All rights reserved 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 bod
14、y 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 closely with the International Electrote
15、chnical 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
16、 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 document may be the subject of patent rig
17、hts. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17282 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.

19、re they compete with traditional materials such as steels and aluminium. In these applications, it is important to achieve a confident knowledge of the safe operating limits of the component through competent design. Computer methods for design are available, and are continually being improved, that
20、 enable predictions to be made of the performance of plastics under a variety of situations. These situations include mechanical performance under service loads and environments as well as a flow of the polymer melt during the manufacture of a component. In order to design effectively with plastics
21、in load-bearing applications, comprehensive data are generally needed which take into account the effects of time, temperature, rate and environment on properties. A number of International Standards have been developed that specify how certain data for plastics should be measured and presented. The
22、se are ISO 10350-1 and ISO 10350-2, and ISO 11403-1, ISO 11403-2 and ISO 11403-3. The purpose of these standards is to enable comparable data to be measured on different materials from different sources to aid the process of materials selection. A substantial quantity of data is specified by these s
23、tandards and, although not the primary purpose of the standards, some of these data are suitable for design. However, additional or alternative data will also be needed for many applications. The purpose of this guide is to augment existing data presentation standards by identifying data that are ne
24、eded specifically for design with plastics. The selection of these data is guided by the requirements of available computer methods for design. Preferred test methods, test specimens and test conditions are recommended in section 5 for determining these data. For some properties, ISO test methods or
