The work of preparing International Standards
27、 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 with ISO, also take p
28、art 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 technical committees is to
29、 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 to the possibility t
30、hat 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 14509-1 was prepared by Technical Committee ISO/TC 188, Small craft. This first edition of ISO 14509-1 cancels and replaces ISO 14509:20
31、00, which has been technically revised. It also incorporates the Amendment ISO 14509:2000/Amd.1:2004.

33、is part of ISO 14509 specifies the conditions for obtaining reproducible and comparable measurement results of the maximum sound pressure level of airborne sound generated during the passage of powered recreational craft of up to 24 m length of hull, including inboards, stern drives, personal waterc
34、raft (PWC) and outboard motors. It also specifies standard craft based type tests for stern drives with integral exhaust systems and for outboard motors. It also specifies the procedure to be followed if, in addition to the maximum sound pressure level, the determination of the sound exposure level
35、is desired. NOTE For craft other than those specified above, ISO 2922 is applicable for sound emission measurements. The accuracy grade of the acoustical test procedures specified in this part of ISO 14509 is engineering grade (grade 2). 2 Normative references The following referenced documents are
