标准摘要
[中文适用范围]： ISO 14509-1规定了在24米及以下的动力休闲船（包括内舷发动机、尾舷发动机、水上摩托艇和个人水上摩托车）通过时，获取最大A计权声压级空气声测量结果的可重复性和可比性条件。它还规定了带有集成排气系统的尾舷发动机和舷外马达的基于标准船型的类型测试。此外，它还规定了如果除了最大声压级外，还需要确定声暴露水平的操作步骤。注：对于未在上述指定的船只，ISO 2922适用于声发射测量。ISO 14509-1规定的声学测试程序的精度等级为工程级（2级）。 [外文原描述]： ISO 14509-1:2008 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 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 sound exposure level is desired. The accuracy grade of the acoustical test procedures specified in ISO 14509-1:2008 is engineering grade (grade 2).
