16、 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 right to be represente

17、d 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. International Standards are draf

18、ted in accordance with the rules given in the ISO/IEC Directives, Part 3. 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 as an International Sta

19、ndard 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 this part of ISO 12215 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 12215-4 wa

20、s prepared by Technical Committee ISO/TC 188, Small craft. ISO 12215 consists of the following parts, under the general title Small craft Hull construction and scantlings: Part 1: Materials: Thermosetting resins, glass-fibre reinforcement, reference laminate Part 2: Materials: Core materials for san

23、age and handling, and requirements for the manufacturing of the craft. It applies, to small craft with a (L H ) length according to ISO 8666 of up to 24 m. This part of ISO 12215 does not cover health and safety requirements. NOTE The underlying reason for preparing this part of ISO 12215 is that wo

24、rkshop conditions have a significant influence on the mechanical short- and long-term properties of recreational craft and that the scantling determination according to ISO 12215-5 is based on conditions that are appropriate for the material used as well as the manufacturing process applied. 2 Norma

25、tive references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 12215. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based o

28、s: Steel, aluminium alloys, wood, other materials 3 Fibre-reinforced plastics (FRP) boat production 3.1 Workshop conditions 3.1.1 General The buildings used for production and storage shall be of suitable construction, and equipped to provide the environment specified by the material manufacturer or

29、 supplier. 1)To be published. SANS 12215-4:2008This standard may only be used and printed by approved subscription and freemailing clients of the SABS.ISO 12215-4:2002(E) 2 ISO 2002 All rights reserved To minimize contamination or impairment of the laminate, the production area shall be separate fro

30、m the storage area and, wherever practicable, the various manufacturing processes shall be carried out in separate sections. The workshop and equipment shall be properly maintained and kept in a clean condition, substantially free from debris, surplus material, and equipment that is not essential fo

31、r the production process. 3.1.2 Temperature and humidity Where a conventional manual lay-up or spray-up process is used, the moulding shop temperature shall be maintained within the limits specified by the resin manufacturer during lay-up and curing periods. Should the temperature vary outside the s

32、pecified limits, the boat builder shall establish with the resin manufacturer that the resulting laminate will meet the requirements upon which scantlings and design are based. The relative humidity in the moulding shop shall be maintained within the limit recommended by the material manufacturers.

33、Materials shall be brought up to the workshop temperature prior to use. The temperature and humidity shall be monitored in appropriate locations, and records shall be kept. 3.1.3 Ventilation Adequate ventilation shall be provided in the laminating area, in order to minimize accumulation of monomer f

34、umes in the mould. The ventilation shall not significantly reduce the surface temperature of the mould or laminate. The design of the ventilation system shall take account of the size of the laminating shop, possible subdivision and the amount of resin under cure. The ventilation arrangements shall

35、not cause excessive evaporation of the resin monomer. Precautions shall be taken to ensure freedom from draughts. 3.1.4 Dust control Provisions shall be made to minimize harmful accumulation of dust on moulds and laminates. 3.1.5 Illumination Provisions shall be made to avoid any harmful effects on

36、the resin cure due to direct sunlight or artificial lighting. 3.2 Material storage and handling 3.2.1 General requirements Storage areas shall be arranged and equipped in such a way that the material manufacturers requirements for storage and handling can be followed. The procedures for the receptio

37、n, verification against certificates of conformity, storage and handling of materials shall be detailed in the conformity assurance procedures provided by the boat builder (see clause 10) to ensure that the materials suffer no contamination or degradation and carry adequate identification at all tim

38、es. Storage shall be arranged so that wherever possible materials are used in order of receipt. Structural parts shall be manufactured from materials that have not passed the material manufacturers date of expiry.

40、uilder. Unused resin and ancillary materials exposed to the workshop atmosphere shall not be returned to the parent stock or bulk storage. 3.2.2 Resin Resins shall be stored under controlled conditions in accordance with the resin manufacturers requirements. Where a resin contains an ingredient that

41、 can settle within the resin system, it is the builders responsibility to ensure that the resin manufacturers recommendations for mixing and conditioning are complied with prior to use. 3.2.3 Catalysts and accelerators Catalysts and accelerators shall be stored according to the material manufacturer

42、s requirements. 3.2.4 Fillers and additives Fillers and additives used in the moulding process shall be stored in closed containers to protect them from dust and humidity. 3.2.5 Reinforcing and core materials Reinforcing and core materials shall be stored in clean and dry conditions, in accordance w

43、ith the material manufacturers recommendations. 3.3 Moulds 3.3.1 Construction Moulds shall be constructed of a suitable material and adequately stiffened to maintain their shape and fairness of form. The materials used in the construction of moulds shall not adversely affect the resin cure. 3.3.2 Pr

44、eparation Moulds shall be cleaned, dried and in place so that they stabilize at the workshop temperature before the release agent is applied. The release agent shall be compatible with the mould surface, the resins applied in the laminating process and with mould release films used previously. Relea

45、se agents containing silicon shall not be used. NOTE Release agents containing silicone oil may interfere with adhesion or secondary bonding when using common resin types. 3.4 Resin preparation The requirements of the resin manufacturer shall be followed. Where blended resins are used, test specimen

46、(s) shall be made to ensure that the blended resin is suitable for the laminating process.

47、fy resin with additives outside the resin manufacturers specification, the boat builder shall conduct tests to verify compliance with Table 3 of ISO 12215-1:2000. 3.5 Laminating process 3.5.1 Manual lay-up The material type and unit weight of the first fibre reinforcement layer shall be chosen to pr

48、ovide for adequate penetration of the reinforcement layer by the resin system used and reduce the effect of hydrolytic attack. The lay-up sequence and degree of resin cure between plies shall be in accordance with the resin manufacturers recommendation. Where the degree of cure exceeds these recomme

49、ndations, the surface shall be treated. Moulds shall be arranged or access provided so that each part of the mould can be reached with the tools used to ensure consolidation and de-aeration of the laminate during lay-up. 3.5.2 Spray lay-up Spray lay-up of resin and/or reinforcement fibres shall be limited to applications where, in general, a specified even thickness of the sprayed laminate can be achieved. Consideration shall be given to exothermic heat by excessive wet laminate thickness, sagging or
