32、7-02 3 1 Scope This 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
33、, personal watercraft (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 soun
34、d exposure level 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 referenc

38、a standard craft, complies with sound specifications or prescribed limits NOTE See also definition of “acceptance test” in ISO 2922. 4EN ISO 14509-1:2008 (E) DIN EN ISO 14509-1:2017-02 3.2 monitoring test for recreational craft monitoring test measurement performed in order to check that the sound o
39、f the craft in motion, or of the outboard motor when using any craft, or of the stern drive with integral exhaust system when using any craft, is still within prescribed limits and that no noticeable changes have occurred since the acceptance on initial delivery or after modification, as applicable
40、NOTE 1 Subsequent type testing can also be required in the case of a significant change.

The application of a specific frequency weighting as specified in IEC 61672-1 is indicated by an appropriate subscript, e.g. EA,1hdenotes the A-weighted sound exposure over one hour. NOTE 3 When applied to a single event of impulsive
44、or intermittent sound, the quantity is called “single event sound exposure” and the symbol E is used without subscript.
