This International Standard specifies the conditions for obtaining reproducible and comparable measurements of the noise level and the noise spectrum emitted by vessels of all kinds on inland water-ways and harbours. This International Standard can also be applied to small sea-going vessels, harbour vessels and dredgers.
In the annex, specifications for intake or exhaust noise measurement and measurements with stationary vessels are given.
NOTES
1 The test procedures specified in this International Standard are engineering methods as defined in ISO 2204, Acoustics — Guide to the measurement of airborne acoustical noise and evaluation of its effects on man. Note, however, that frequency band analysis is only required for type tests.
2 Measurements may be made on sources emitting noise of an impulsive character with an impulse sound level meter (see clause 5).
