The work of preparing International Standards is normally carried out through ISO t
18、echnical 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, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clos
19、ely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria n
20、eeded for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of paten

26、 to be used in determining the properties of polypropylene (PP) moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given.Procedures and conditions for the preparation of test speci
27、mens and procedures for measuring properties of the materials from which these specimens are made are also given. Properties and test methods which are suitable and necessary to characterize PP moulding and extrusion materials are listed.The properties have been selected from the general test method
28、s in ISO 10350-1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this part of ISO 19069, as are the designatory properties specified in ISO 19069-1.In order to obtain reproducible and comparable test results, it is ne
29、cessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.2 Normative referencesThe

44、rocedure (either injection moulding or compression moulding), and under the same processing conditions.The procedure to be used for each test method is indicated in Tables 3 and 4 (M = injection moulding, Q = compression moulding).3.2 Treatment of the material before mouldingPre-treatment of the mat
45、erial sample is normally not necessary before moulding.3.3 Injection mouldingInjection-moulded specimens shall be prepared in accordance with ISO 294-1 or ISO 294-3, under the conditions specified in Table 1. It has been found that bar test specimens prepared in accordance with ISO 20753 give better
46、 precision than those injection-moulded directly to their final dimensions, and so the use of this geometry is preferable.An appropriate hold pressure, consistent with the production of blemish-free mouldings, shall be used.Table 1 Conditions for injection moulding of test specimensMaterial Melt tem
