The work of preparing International Standards is

11、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 organizations, governmental and non-governmental, in liaison with ISO, also take part

12、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 the ISO/IEC Directives, Part 3. The main task of technical committees is to pre

13、pare International Standards. 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

14、some of the elements of this part of ISO 1268 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 1268-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 13, Composites and reinforcement fibres. Together wi

15、th 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 parts, under the general title Fibre-reinforced plastics Methods of producing test plates: Part 1: General conditions Part 2: Contact and s

16、pray-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 Part 8: Compression moulding of SMC and BMC Part 9: Moulding of GMT/STC Part 10: Injection moulding of SMC and other long-fibre moulding

18、e various parts of ISO 1268 (see the foreword) describe methods used to prepare reinforced-plastics plates from which test specimens can be cut. This allows the properties of a composite, or the constituents of the composite, to be determined. The methods are intended to cover all the main types of

19、reinforcement and resin matrix. The choice of test plate preparation method depends on: a) the reinforcement: its nature (glass, carbon, aramid, etc.); its form (roving, mat, woven fabric, etc.); its orientation with respect to the length, width and thickness of the plate; its content in the reinfor

20、ced plastic; b) the matrix (thermosetting or thermoplastic); c) the magnitude expected for the properties; d) the production process that is to be evaluated. Since the mechanical properties of a reinforced plastic are known to be dependent on the process by which the plastic is produced, it is recom

21、mended that the test plates be prepared, if possible, by the same method that will be used to produce the plastic. This part of ISO 1268 describes the general requirements common to all the methods. 2 Normative references The following normative documents contain provisions which, through reference

22、in this text, constitute provisions of this part of ISO 1268. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 1268 are encouraged to investigate the possibility of applying the most rece

23、nt editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 472, Plastics Vocabulary ISO 1172, Textile-glass-reinforced plas

26、terms and definitions given in ISO 472 apply. Each subsequent part of ISO 1268 gives, where necessary, the definitions of specific terms it needs to introduce. 4 Health and safety The various parts of ISO 1268 are limited to describing test plate preparation methods. The conditions under which the m

27、aterials used are handled shall comply with the national regulations in force in each country and the staff shall be informed of the hazards involved and appropriate precautions taken. 5 Principle Subsequent parts of this International Standard describe the basic methods utilized to produce test pla

28、tes. 6 Raw materials and semi-finished products All the materials used (reinforcements, resins, additives; SMC, BMC, prepregs, etc.) shall be identified in a precise manner. They shall be stored under the conditions recommended by the manufacturer and shall be used before the expiration date marked

29、on the label. 7 Plate dimensions The length, width and thickness of the plates produced will depend on the material being processed and the method used to produce them. The dimensions shall be as specified in the relevant part of this Intenational Standard. NOTE The plate dimensions will also depend

30、 on the test which will be conducted on the test specimens cut from the plates. For example, a square plate of side at least 250 mm is required to perform tensile tests in two perpendicular directions. 8 Reinforcement The reinforcement content of the plate shall be the same as in the finished produc

31、ts whose properties are to be evaluated. In the absence of particular specifications, use the recommended content given in the relevant part of this International Standard. 9 General requirements for the laboratory/workshop apparatus Unless otherwise specified, the apparatus used to produce the plat

32、es shall be capable of maintaining the required temperatures and pressures to within the accuracy prescribed for the chosen plate production method. ISO 1268-1:2001(E) 3The laboratory/workshop shall be equipped with monitoring equipment which will enable the production temperature and pressure to be

33、 recorded as a function of time. 10 Procedure The procedure used to prepare the test plates will differ depending on the process and materials used. The procedure to be followed for a particular plate production method is described in the relevant part of this International Standard. 11 Verification

34、 of the characteristics of the plates obtained 11.1 General The plates obtained shall be inspected prior to cutting out test specimens. The criteria for acceptance or rejection of a plate shall be as defined in the materials specifications and in the plate production method, or as agreed between the

35、 interested parties. 11.2 Fibre content The fibre content shall be determined in accordance with ISO 1172 for glass-reinforced plastics and by a method agreed on between the interested parties for carbon-reinforced plastics. The lay-up sequence can be determined by examination of the residue. 11.3 D

36、egree of porosity or void content The degree of porosity, or void content, is a measure of the frequency of occurrence of open or closed cavities in the plate. Any of several methods may be used to determine it: visual examination, examination of a polished cross-section using a microscope (see ISO

37、7822), ultrasonic examination or X-ray examination. 11.4 Density The density may be determined in accordance with the appropriate part of ISO 1183. 11.5 Dimensions The thickness of the plates shall be measured and, where necessary, the other dimensions. 12 Marking Each plate shall be marked to allow

38、 the identification of the mould or the mould cavity used; the side of the plate; the lay-up sequence, if required; the orientation of the plate with respect to the melt flow direction, or to any other direction specific to the material or the method of production. ISO 1268-1:2001(E) 4 The system of

39、 lines (thin or broad, single or multiple) described in ISO 10724-2:1998, annex C, shall be used. In addition, plates shall have markings enabling the plate preparation report to be easily traced. 13 Test plate preparation report The test plate preparation report shall indicate the following informa

40、tion: a) a reference to the relevant part of this International Standard; b) the place and date of production of the plate or plates; c) a full description of the materials used, including details of resins, reinforcements, fillers, etc.; d) the composition of the resin system used, where applicable

41、; e) a description of the equipment used; f) details of the operating conditions; g) details of the lay-up of the plate or plates; h) the values of the test plate characteristics (e.g. thickness, fibre content) which the relevant part of this International Standard requires to be determined and any

42、other characteristics when applicable (see clause 11); i) any other information needed to reproduce the plates exactly; j) any deviations from the relevant part of this International Standard. blankBS ISO 1268-1:2001 BSI 389 Chiswick High Road London W4 4AL BSI British Standards Institution BSI is t
