9、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 right to be represented on that committee. International organizat
10、ions, 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. International Standards are drafted in accordance with the rules given in th
11、e ISO/IEC Directives, Part 3. 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

It applies exclusively to glass reinforcements. It is inten
17、ded to be read in conjunction with ISO 1268-1. 2Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 1268.

The resin is formulated in accordance with the man
21、ufacturers instructions to attain cure within a pe- riod of time that allows completion of the lay-up, yet limits unnecessary exposure to the atmosphere. The glass fibre and resin are consolidated by means of a hand-operated roller. This method is suitable for any thermosetting resin that cures at r
22、oom temperature without the need for additional pressure to be applied. -,-,- ISO 1268-2:2001(E) 2 ISO 2001 All rights reserved 4.2Spray-up moulding Textile glass rovings are chopped to predetermined lengths in a cutter and simultaneously combined with a stream of tiny resin droplets emerging from a
23、 spray-gun nozzle. This method is normally used with unsaturated-polyester res- ins. Glass fibre and resin are dispersed on a rigid flat plate or a mould, and consolidated by means of a hand-operated roller. 5Materials 5.1Contact moulding 5.1.1Layers of reinforcing material, cut to the dimensions of
24、 the test plate, marking the warp and weft or pre- ferred direction when appropriate. Suitable materials include chopped-strand mats with a binder that is soluble in the resin mix, woven fabrics made from rovings or yarns, multiaxial non-woven fabrics, etc. 5.1.2Thermosetting resin and curing agents
