The work of preparing In
19、ternational 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 organizations, governmental and non-governmental, in liaison
20、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 the ISO/IEC Directives, Part 2. The main task of techn
21、ical 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 Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn
22、 to the possibility that some of 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 14509-2 was prepared by Technical Committee ISO/TC 188, Small craft. ISO 14509 consists of the following parts, und

24、006vIntroduction The development of this part of ISO 14509 became necessary in order to provide an assessment procedure which would satisfy the needs of the European Union Directive 2003/44/EC (Amendment to Directive 94/25/EC). The reason for the inclusion of this type of assessment procedure in the
25、 Directive is to try to minimize the economic impact of the Directive on the boating industry, in particular small European boat builders, while still providing an environmental benefit to the community through lower sound levels.

26、d recreational craft Part 2: Sound assessment using reference craft 1 Scope This part of ISO 14509 specifies the procedures to assess the maximum sound emission of powered mono-hull recreational craft of up to 24 m length according to one of the two alternative methods defined in Annex A and Annex B
27、. This part of ISO 14509 is not applicable for the type testing of outboard motors and of stern drives with integral exhaust systems. 2 Normative references The following referenced documents are indispensable for the application of this document.

33、dditionally the mass of the number of persons needed for the safe operation of the boat and the mass of the fuel (i.e. at least at 25 % but no more than 50 % of the tank capacity of permanently installed fuel tanks, or one portable tank per engine at least 50 % full at the beginning of each test tri
34、al), but excludes the mass of fresh water, waste water, provisions and other loose equipment NOTE 1 This definition is in conformity with ISO 8666:2002, 6.4. NOTE 2 Loose equipment needed for the safe operation of the boat includes warps, anchors/chain/ropes, working sails, engine(s) and batteries;
35、other loose equipment includes cutlery, crockery, kitchen utensils and spare parts. 3.5 insertion loss reduction of the exhaust-outlet sound power level due to the insertion of the vessels silencing system in place of a substitution duct NOTE Insertion loss is expressed spectrally in decibels and is
36、 dependent upon the source impedance of the engine. 3.6 substitution duct duct with the same length as the vessels silencing system and with as constant a cross-sectional area as possible, that is designed to be fitted in place of the vessels silencing system 4 Symbols The following symbols are used

40、hall be compared with those of an appropriate reference boat, according to the assessment method selected, which is either the “insertion loss measurement method” defined in Annex A or the “sound pressure level over stern measurement method” defined in Annex B. If the key parameters are within the s
41、tated tolerances for each and every item listed in the relevant annex (indicating “yes” in every line of Table A.1 or Table B.1), the maximum AS-weighted sound pressure level of the boat is assessed to be not more than 2 dB higher than that of the reference boat. 7 Assessment report The assessment r
