Scope
This standard specifies the engineering and simplified methods for measuring sound pressure levels and determining noise power on the imaginary rectangular hexahedron measuring surface of marine diesel engines (hereinafter referred to as diesel engines) when they are operating under specified steady-state conditions.
This standard applies to the measurement of airborne noise radiated by diesel engines during bench tests.
