Reciprocating internal combustion engines. Measurement method for air cleaners. Sound power level of combustion air inlet noise and insertion loss using sound pressure has-tracked-changes "General requirements"1 Scope This Technical Specification specifies the measurement method and requirements for combustion air inlet noise of air cleaners which are installed on reciprocating internal combustion engines, including laboratory measurement (engineering method and survey method) and site measurement (survey method). This Technical Specification applies to all air cleaners installed on reciprocating internal combustion engines (reciprocating internal
