The work of preparing International Standards is normally carried out throug
8、h ISO technical 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 collaborat
9、es closely with the International 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 Standard
10、s. Draft International Standards 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 thi

ISO 1873-2 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This third edition cancels and replaces the second edition
12、(ISO 1873-2:1997), which has been technically revised. It also incorporates the Amendment ISO 1873-2:1997/Amd.1:2000.

14、of ISO 1873 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of PP moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testin
15、g are given. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize PP moulding and extrusion materials are li
16、sted. The properties have been selected from the general test methods 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 1873, as are the designatory properties specified in Part 1. In ord
17、er to obtain reproducible and comparable test results, it is necessary 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 o
18、r prepared using different procedures. 2 Normative references The following referenced documents are indispensable for the application of this document.
