Technical Guide to Sound Testing
From 1 January 2006 every CI and 4 stroke internal combustion engine recreational craft, including sailing boats with auxiliary engines, that are placed on the market and/or put into service within the European Union must comply with the sound regulations set out in EU Directive 2003/44/EC.
It is also compulsory for 2 stroke engines from 1 January 2007. Optional from 1 January 2005.
Work is currently being completed in the ISO Working Group for Sound on the following amendments to EN ISO 14509:
Next Steps
Part 1. This will incorporate the existing pass-by test standard but hopefully with a relaxation of some of the atmospheric and weather related criteria.
Part 2. This will incorporate the Reference Boat method described in the directive. This should allow a boat to be assessed by comparison with data derived from other craft that have successfully passed the test in Part 1 and whose information is available in a published database.
Sound Boat. An EU funded project to seek alternative methods of sound assessment is progressing well and much experience gained from the project is already being incorporated into current practise. A predictive methodology incorporating on-board sound measurement and certain hull parameters is to be developed as EN ISO 14509-3.
However it is only now being considered as a New Work Item by ISO, so a harmonised standard using this Technical Guide to Sound Testing method is unlikely to be available until late in 2005.
News of these developments will become available through MIAs, Notified Bodies and the ICOMIA website.
