23、SO (the International Organization for Standardization) is a 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 c
24、ommittee 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 the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electr
25、otechnical 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 International Standards. Draft International Standards adopted by the technical committees are circulated to the m
26、ember 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 of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identi
27、fying any or all such patent rights. ISO 14509-3 was prepared by Technical Committee ISO/TC 188, Small craft. ISO 14509 consists of the following parts, under the general title Small craft Airborne sound emitted by powered recreational craft: Part 1: Pass-by measurement procedures Part 2: Sound asse
28、ssment using reference craft Part 3: Sound assessment using calculation and measurement procedures BS EN ISO 14509-3:2009ISO 14509-3:2009(E) ISO 2009 All rights reserved vIntroduction The European Union Directive 2003/44/EC (Amendment to Directive 94/25/EC) introduces limits for sound emission from
29、recreational craft and requires conformity for certain types of craft to be shown by using the ISO 14509 series. ISO 14509-1 provides a practical measurement method, ISO 14509-2 provides an assessment method using reference craft and this part of ISO 14509 provides a predictive measurement method ba
30、sed on the work of the SoundBoat project. SoundBoat was funded by the European Commission and various European Marine Industry Associations and industrial partners to develop alternative methods of testing sound emission from recreational craft. Over the two years of the project, more than 65 craft
31、have been tested according to the ISO 14509-1 pass-by test. From this an algorithm has been developed that uses a combination of hullwater sound, derived from hull parameters, and exhaust outlet sound, derived by direct measurement on board the craft under test, to predict the sound pressure level t
32、hat would be observed at 25 m had the craft undergone pass-by testing according to ISO 14509-1. The method specified in this part of ISO 14509 does not require a measurement platform to be established and testing can be carried out independently of location and weather restrictions. This method does
33、 not require a list of reference craft to be established and provides a reproducible assessment procedure comparable to ISO 14509-1 pass-by testing to within 2 dB. The SoundBoat project has concentrated on specific craft types and has only tested craft with the following characteristics: bottom type
34、 configuration of not more than two chines; square transom configuration; length of hull 11 m or greater. The SoundBoat project was successfully completed in early 2005, but industry continues to gather data from on-water testing and, as the data model is refined with further validation of the conce
35、pt, the parameters above will be revised appropriately. The SoundBoat project team do not believe that craft outside the above characteristics are unsuitable for assessment using this part of ISO 14509; however, where a significantly different craft is to be assessed, it might be beneficial to test
36、according to ISO 14509-1.
