26、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 repres
27、ented 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. Draft International Standard
28、s 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 bodies casting a vote. International Standard ISO 11403-3 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommit
29、tee SC 2, Mechanical properties. 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 Part 3: Environmental influences on properties Owing to the
30、 wide range of properties that are included in ISO 11403, it has been necessary to develop the standard in stages, dividing the contents into parts. In this way, each part can be further developed separately and further parts can be added when appropriate. Annex B forms an integral part of this part
31、 of ISO 11403. Annex A is for information only. EN ISO 114033:2001 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 02:34:50 GMT+00:00 2006, Uncontrolled Copy, (c) BSI )E(9991:3-30411 OSI OSI iv Introduction This International Standard has been prepared because users of plastics find sometimes
32、 that available data cannot be used readily to compare the properties of similar materials, 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 o
33、btained are not necessarily comparable. The purpose of this International Standard is to 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. These data are not necessarily suitable for
34、 design. ISO 103501) is concerned with single-point data. Such data represent the most basic method for characterizing materials and are useful for the initial stages of material selection. The present International Standard identifies test conditions and procedures for the measurement and presentat
35、ion of a more substantial quantity of data. Each property here is characterized by multipoint data which demonstrate how that property depends upon important variables such as time, temperature and environmental effects. Additional properties are also considered in this standard. These data therefor
36、e enable more discriminating decisions to be made regarding the materials suitability for a particular application. Some data are also considered adequate for undertaking predictions of performance in service and of optimum processing conditions for moulding a component, although it should be recogn
37、ized that, for purposes of design, additional data will often be needed. One reason for this is that some properties are strongly dependent upon the physical structure of the material. The test procedures referred to in this standard employ standard test specimens, and the polymer structure in these
38、 specimens may be significantly different from that in specific regions of a moulded component. Under these circumstances, 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 appl
39、icability of data. ISO 10350 and the various parts of this International Standard together define the means for acquiring 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
40、 with provision of these data. Furthermore, reference to these standards will simplify the development of data models for 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 ho
41、wever, owing to the wide range of conditions over which different plastics perform, the standard gives guidance in the selection of certain test conditions so that they cover the operating range for that polymer. Because, in general, the properties and performance specifications for different polyme
42、rs differ widely, there is no obligation to generate data under all the test conditions specified in this standard. Data on 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 experimen
43、tal procedures which are suitable for the acquisition of relevant information on many of these properties. For other properties, 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 h
44、as therefore been divided into parts so that each part can be developed independently. In this way, additional properties can be included as new or revised standards become available. 1) ISO 10350-1:1998, Plastics Acquisition and presentation of comparable single-point data Part 1: Moulding material

46、1 OSI 1 Plastics Acquisition and presentation of comparable multipoint data Part 3: Environmental influences on properties 1 Scope This part of ISO 11403 specifies test procedures for the acquisition and presentation of multipoint data which demonstrate the behaviour of plastics under the following
47、environments: prolonged exposure to heat; liquid chemicals; environmental stress cracking under a constant tensile stress; artificial weathering. The tests are listed in order of increasing severity of the environment. By testing under the least severe environments first, it is possible to make info
48、rmed judgements regarding whether tests under more severe conditions are worthwhile. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 11403. At the time of publication, the editions indicated were valid
49、. All standards are subject to revision, and parties to agreements based on this part of ISO 11403 are encouraged to investigate the possibility of applying the most recent editions of the standards listed below.
