Reciprocating internal combustion engines. Test code for the measurement of structure-borne noise emitted from high-speed and medium-speed reciprocating internal combustion engines measured at the engine feet Ingestion-build-159183 open-circuit breathing apparatus (SCBA) intended1 Scope This International Standard defines the procedure for measuring the capacity of a high speed or medium speed engine to generate vibration and the determination of the frequency limits of validity of the information quoted. The method described in this International Standard is not suitable for low speed engines. This International Standard describes an engineering and not a precision method. Whether the tests are carried out on the test bed or
