9、 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 interested in a subject for which a technical committee has been established has the
10、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 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Internatio
11、nal 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 Standards adopted by the technical committees are circulated to the member bodies for voting. Publication a
12、s an International Standard requires approval by at least 75 % of the member bodies casting a vote.

13、SO 1268-11 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. Together with the other parts (see below), this part of ISO 1268 cancels and replaces ISO 1268:1974, which has been technically revised. ISO 1268 consists of the following par
14、ts, under the general title Fibre-reinforced plastics Methods of producing test plates: Part 1: General conditions Part 2: Contact and spray-up moulding Part 3: Wet compression moulding Part 4: Moulding of prepregs Part 5: Filament winding Part 6: Pultrusion moulding Part 7: Resin transfer moulding
15、Part 8: Compression moulding of SMC and BMC Part 9: Moulding of GMT/STC Part 10: Injection moulding of BMC and other long-fibre moulding compounds General principles and moulding of multipurpose test specimens Part 11: Injection moulding of BMC and other long-fibre moulding compounds Small plates -,
16、-,- ISO 1268-11:2005(E) ISO 2005 All rights reserved v Introduction Many factors in the injection-moulding process can influence the properties of moulded test specimens and hence the measured values obtained when the specimens are used in a test method. The thermal and mechanical properties of such
17、 specimens are in fact strongly dependent on the conditions of the moulding process used to prepare the specimens. Exact definition of each of the main parameters of the moulding process is a basic requirement for reproducible and comparable operating conditions. It is important in defining moulding
18、 conditions to consider any influence the conditions may have on the properties to be determined. Thermosets may show differences in orientation and length of anisotropic fillers such as long fibres and in curing. Residual (“frozen-in”) stresses in the moulded test specimens may also influence prope
19、rties. Due to the crosslinking of thermosets, molecular orientation is of less influence on mechanical properties than it is for thermoplastics. Each of these phenomena must be controlled to avoid fluctuation of the numerical values of the measured properties. The principles described in this part o
20、f ISO 1268 are the same as those in ISO 10724-2. Only a few details of the moulds have changed, as has specimen thickness, because of the use of long-fibre reinforcements. It is therefore possible to compare the properties of long-fibre moulding compounds with those of thermosetting powder moulding
21、compounds (PMCs) and thermoplastics. -,-,- -,-,- INTERNATIONAL STANDARD ISO 1268-11:2005(E) ISO 2005 All rights reserved 1 Fibre-reinforced plastics Methods of producing test plates Part 11: Injection moulding of BMC and other long-fibre moulding compounds Small plates 1 Scope This part of ISO 1268
22、specifies two two-cavity moulds, designated the type D1 and type D2 ISO moulds, for the injection moulding of small plates measuring 60 mm 60 mm with preferred thicknesses of 2 mm (type D1) or 4 mm (type D2) which can be used for a variety of tests (see Annex A). The moulds may additionally be fitte
23、d with inserts for studying the effects of weld lines on the mechanical properties (see Annex B). This part of ISO 1268 is intended to be read in conjunction with ISO 1268-1. 2 Normative references The following referenced documents are indispensable for the application of this document.
