18、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 interested in a subject for which a technical committee
19、 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 Electrotechnical Commission (IEC) on all matters of electrotechnic
20、al 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 technical committees are circulated to the member bodi
21、es 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. ISO shall not be held responsible for identifying any o
22、r all such patent rights.ISO 11403-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.This third edition cancels and replaces the second edition (ISO 11403-2:2004), of which it constitutes a minor revision to amend “moulding temperature” to “mould tem
23、perature” in the last column in Table 1, to update the note in 6.2 and to update Annex A.ISO 11403 consists of the following parts, under the general title Plastics Acquisition and presentation of comparable multipoint data: Part 1: Mechanical properties Part 2: Thermal and processing properties Par
24、t 3: Environmental influences on propertiesiv ISO 2012 All rights reservedBS EN ISO 11403-2:2012ISO 11403-2:2012(E)IntroductionThis International Standard has been prepared because users of plastics find sometimes that available data cannot be used readily to compare the properties of similar materi
25、als, especially when the data have been supplied by different sources. Even when the same standard tests have been used, they often allow the adoption of a wide range of alternative test conditions, and the data obtained are not necessarily comparable. The purpose of this International Standard is t
26、o identify specific methods and conditions of test to be used for the acquisition and presentation of data in order that valid comparisons between materials can be made.ISO 10350 is concerned with single-point data. Such data represent the most basic method for characterizing materials and are usefu
27、l for the initial stages of material selection. The present International Standard identifies test conditions and procedures for the measurement and presentation of a more substantial quantity of data. Each property here is characterized by multipoint data which demonstrate how that property depends
28、 upon important variables such as time, temperature and environmental effects. Additional properties are also considered in this standard. These data therefore enable more discriminating decisions to be made regarding a materials suitability for a particular application. Some data are also considere
29、d adequate for undertaking predictions of performance in service and of optimum processing conditions for moulding a component, although it should be recognized that, for purposes of design, additional data will often be needed. One reason for this is that some properties are strongly dependent upon
30、 the physical structure of the material. The test procedures referred to in this standard employ, where possible, the multipurpose tensile bar, and the polymer structure in this test specimen may be significantly different from that in specific regions of a moulded component. Under these circumstanc
31、es, therefore, the data will not be suitable for accurate design calculations for product performance. The material supplier should be consulted for specific information on the applicability of data.ISO 10350 and the various parts of this International Standard together define the means for acquirin
32、g and presenting a core set of comparable data for use in material selection. Use of these standards should result in a rationalization of effort and a reduction of cost associated with provision of these data. Furthermore, reference to these standards will simplify the development of data models fo
33、r the computerized storage and exchange of data concerning material properties.Where appropriate, values for test variables have been specified by this standard. For some tests however, owing to the wide range of conditions over which different plastics perform, the standard gives guidance in the se
34、lection of certain test conditions so that they cover the operating range for that polymer. Because, in general, the properties and performance specifications for different polymers differ widely, there is no obligation to generate data under all the test conditions specified in this standard.Data o
35、n a wide range of properties are needed to enable plastics to be selected and used in the large variety of applications to which they are suited. ISO standards describe experimental procedures which are suitable for the acquisition of relevant information on many of these properties. For other prope
36、rties, however, ISO standards either do not exist or exhibit shortcomings that complicate their use at present for the generation of comparable data (see Annex A). The standard has therefore been divided into parts so that each part can be developed independently. In this way, additional properties
37、can be included as new or revised standards become available.
