11、:2008ISO 24453:2008(E) iv ISO 2008 All rights reservedForeword 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.
12、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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internat
13、ional Electrotechnical 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 Stand
14、ards 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. Attention is drawn to the possibility that some of the elements of this document may be the subjec
15、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 24453 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Testing and analysis. BS ISO 24453:2008INTERNATIONAL STANDARD ISO 24453:2008(E) ISO 2008 All ri

In general, each property is specified b
17、y a single test method and a single experimental value although, in certain cases, properties may be represented by more than one value obtained under different test conditions. The properties presented are those used to characterize processing properties, those most often quoted by manufacturers an
18、d in material specifications, and those relevant to more specific applications. An important application of this International Standard consists in helping different suppliers produce material specification sheets in which the same set of properties is measured using the same conditions. 2 Normative

34、erms and definitions apply. 3.1 single-point data data characterizing a rubber material by means of those property tests in which important aspects of performance can be described with single-value results 4 Test piece preparation Where relevant, materials for test shall be prepared, mixed and mould
35、ed following the general principles given in ISO 2393. The detailed conditions used shall be as recommended by the manufacturer of the rubber compound and shall, for each of the processing steps, be the same for each test piece except that different cure times may be used for different sized test pi
36、eces. The equipment, mixing cycle and conditions used for moulding shall be given in the test report. The final preparation of test pieces (for example stamping from sheet) shall be in accordance with the relevant test method standard. The properties of a rubber compound can vary depending on the pr
37、ocessing procedures used and this should be taken into account when comparing materials. To maximize the usefulness of results, processing conditions should be representative of those used in production. 5 Conditioning The time between mixing and moulding shall be between 24 h and one week. The time
38、 between moulding and conditioning shall be between 16 h and four weeks. Recommendations for the storage of vulcanized rubber products are given in ISO 2230. Test pieces shall be conditioned in accordance with the relevant test method standard. Where this refers to standard laboratory conditions of
39、temperature and/or humidity, these are taken to mean (23 2) C and 50 % RH. NOTE If tests are carried out at the alternative standard laboratory temperature of (27 2) C, the results will not be strictly comparable unless adjusted by the known relationship of the property with temperature. For tests a
40、t temperatures other than (23 2) C, where specific instructions are not included in the test method standard, condition the test pieces at the temperature at which the test is to be conducted for a period sufficient to enable test pieces to attain substantial equilibrium in accordance with ISO 23529
41、. Details of the conditioning used shall be given in the test report. BS ISO 24453:2008ISO 24453:2008(E) 4 ISO 2008 All rights reserved6 Processability properties If processability data are required (for example if unvulcanized material is being supplied), the test methods, test conditions and units
42、 shall be selected from those specified in Table 1. The test temperature(s) shall be as considered appropriate for the material in question. NOTE The measurement of viscoelastic flow and cure properties of rubber compounds is essential for the processor in order to form the material efficiently and
43、effectively into the required product. However, these properties are generally of little consequence for the end user of the product and it is for this reason that processability properties are considered separately to other properties in this International Standard.

47、s specified in Table 2 shall be used when determining data according to this International Standard. A property may be omitted if it is not relevant to the material in question (for example fluid resistance, if a compound is not for use in oil or fuel). It is not essential to measure both compressio
48、n and tension set, the choice being dependent on the material and the intended application. If required, additional properties may be presented using the test methods, test conditions and units specified in Table 3. It is recommended that all properties relevant to the intended end use of the materi
