Hydraulic fluid power. Test code for the determination of sound power levels using sound intensity techniques. Engineering method - Pumps Ingestion-build-46800 or regarded as optional1 Scope This part of ISO 16902 establishes a test code based on ISO 9614 1 and ISO 9614 2 for determining the sound power levels of a hydraulic fluid power pump under controlled conditions of installation and operation. The sound power level will include sound power radiated by any piping within the measurement surface. This part of ISO 16902 is suitable for providing a basis for comparing the airborne noise levels of any type of pump that is normally
