18、9(E)iv ISO 2009 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. Each member body in
19、terested in a subject for which a technical committee has beenestablished 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 closelywith the International Electrotechnica
20、l 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 Standardsadopted by the tec
21、hnical 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 rights. ISO
22、 shall not be held responsible for identifying any or all such patent rights. ISO 25137-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplasticmaterials.

Requirements forhandling test material and for conditioning both the test material before moulding and the specimens before testing are given here.1.2 Procedures and conditions for the preparation of test specimens and procedures for measuringproperties of the materials from which these specimens
26、are made are given. Properties and test methodswhich are suitable and necessary to characterize sulfone polymer moulding and extrusion materials are listed. 1.3 The properties have been selected from the general test methods in ISO10350-1. Other test methodsin wideuse for, or of particular significa
27、nce to, thesemoulding and extrusion materials are alsoincluded in thispart of ISO25137, as are the designatory properties specified in Part1. 1.4 In order to obtain reproducible and comparable test results,it is necessary to use the methods of specimen preparation and conditioning, the specimen dime

The procedure to be used for each test method is indicated in Table 2.3.2Treatment of the material before moulding Before moulding, the material shall be dried to a moisture level of no more than 0,05 % as determined
40、using ISO 15512. 3.3 Injectionmoulding Injection-moulded specimens shall be prepared in accordance with ISO 294-1, using the conditions specified in Table 1.

The recommen
42、ded drying conditions forthese specimens are 2 h at 160 C. The target moisture level is 300 ppm. Test specimens for temperature of deflection under load shall be annealed as per Table 2 before conditioning for at least 24 h at (23 2)Cand (50 10) % relative humidity. Test specimens for other properti
43、es shall be conditioned forat least 24 hat (23 2) C and (50 10) % relative humidity. 5 Determination of properties In the determination of properties and the presentation of data, the standards, supplementary instructions and notes given in ISO10350-1 shall be applied. All tests shall be carried out
44、 in one of the standard atmospheresin ISO 291 unless specifically stated otherwisein Table 2. A testatmosphere of (23 2) C and (50 10) % relative humidity shall be used in cases of dispute.
