The work of preparing International Standards is nor
27、mally 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 in
28、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 2.The main task of technical committees is to prepare
29、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 some o
30、f the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 21487 was prepared by Technical Committee ISO/TC 188, Small craft.This second edition cancels and replaces the first edition (ISO 21487:2006), whic
31、h has been technically revised. It also incorporates the Technical Corrigendum ISO 21487:2006/Cor.1:2008. The main changes from the first edition are the following: diesel tanks shall be equipped with inspection hatch(es) for cleaning and inspection (4.3.10); metallic tanks may be static pressure te
32、sted as an alternative to the pressure-impulse test (5.2.2); non-metallic, non-integral tanks, if installed in an engine compartment, shall be fire tested (6.2.3); non-metallic tanks shall be marked with the maximum temperature to which the tank may be exposed (Clause 8).iv ISO 2012 All rights reser

42、or compounds with which the material can come in contact as installed under normal operating conditions, e.g. grease, lubricating oil, bilge solvents and sea water.4.2 Copper-based alloysCopper-based alloys for fittings are acceptable for direct coupling with all tank materials specified in Table 1,
43、 except aluminium. Copper-based alloy fittings are allowed for aluminium tanks only if a galvanic barrier is arranged between fitting and tank.4.3 Provisions to tanks4.3.1 There shall be provisions to determine the fuel level or quantity in the tank considering also the requirements in 5.1.2 for pet
44、rol fuel tanks and 6.1.3 for diesel fuel tanks.4.3.2 Metal tanks shall be designed or installed so that no exterior surface will trap water.4.3.3 All rigid tubes and pipes which extend near the tank bottom shall have sufficient clearance to prevent contact with the bottom during normal operation of
45、the craft.4.3.4 On metallic tanks, all metallic non-integral tank supports, chocks or hangers shall either be separated from the surface of the tank by a non-metallic, non-hygroscopic, non-abrasive material or welded to the tank.4.3.5 If baffles are provided, the total open area provided in the baff
46、les shall be not greater than 30 % of the tank cross section in the plane of the baffle.4.3.6 Baffle openings shall be designed so that they do not prevent the fuel flow across the bottom or trap vapour across the top of the tank.4.3.7 The fuel fill pipe on the tank shall have a minimum inside diame
47、ter of 28,5 mm.4.3.8 Each ventilation pipe on the tank shall have a minimum inside diameter of 11 mm (95 mm2) or a ventilation opening designed to prevent the tank pressure from exceeding 80 % of the maximum test pressure marked on the tank label when tested in accordance with ISO 10088.4.3.9 Suitab
48、le metallic tank materials and minimum recommended material thicknesses required for corrosion resistance are given in Table 1. Other materials may be used if they demonstrate equivalent fuel and corrosion resistance.4.3.10 Diesel tanks shall be equipped with inspection hatch(es) having a suitable d
49、iameter of at least 120 mm at suitable position(s) for cleaning and inspection of the lowest part(s) of the tank. The hatch must remain accessible when the tank has been installed in the craft. The hatch(es) may be located on the top or side of the tank.2 ISO 2012 All rights reservedCopyright European Commi
