11、O 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 represented on that committee. International organizations, gove
12、rnmental 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 are drafted in accordance with the rules given in the ISO/IEC
13、Directives, Part 2. 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 International Standard requires approval by at least 75 % of the member
14、 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. 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, Subcommitt

ISO 17282:2004(E) ISO 2004 All rights reserved vIntroduction Plastics and composites are increasingly being used in load-bearing applications where they compete with traditional materials such as steels and aluminium. In these applications, it is important to achieve
16、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 enable predictions to be made of the performance of plastics under a variety of situations. These situations include mecha
17、nical 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 in load-bearing applications, comprehensive data are generally needed which take into account the effects of time, temperat
18、ure, 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. These 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 enab
19、le 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 standards and, although not the primary purpose of the standards, some of these data are suitable for design. However, addit
20、ional 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 needed specifically for design with plastics. The selection of these data is guided by the requirements of available computer
21、 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 specimens are not yet available. Reference is then made in the Notes to Tables 6 and 7 to suitable procedures for data acq
22、uisition that may become standardised at a later stage. It is intended that this guide assist the development of databases that will interface with computer methods for design so that the property data required by these methods can be readily accessed. For certain properties, some analysis and inter
23、pretation of data is needed in order to present information in the form required by the design analysis. Some procedures for data analysis are described in the annexes.

24、 data 1 Scope This International Standard gives guidelines for the acquisition and presentation of data that can be used for design with plastics. Emphasis is given to the acquisition of data needed by computerised methods for design. It includes data needed for the analysis of the flow of polymer m
25、elts during the manufacture of a component as well as data needed for the prediction of mechanical performance of the component in service. The data requirements cover design with unfilled plastics as well as filled, short-fibre reinforced and continuous-fibre reinforced materials. 2 Normative refer
