EUROLAB, with its state-of-the-art accredited laboratories and expert team, offers precise and rapid testing services within the scope of EN 1151-2 testing. This part of EN 1151 specifies a test code for the vibration-acoustic characterization of circulation pumps as defined in EN 1151-1 and is limited to circulation pumps with 1½ inch threaded connections. The test code includes the test hardware, measurement method, and test conditions.
The characterization principle is based on measuring the structure-induced and fluid-induced power transmitted through vibration and pressure fluctuations, respectively, in the pipe connected to a circulation pump.
This part of EN 1151 covers the measurement of fluid and structure-borne noise caused by small circulation pumps. It was prepared in response to the need to have uniform procedures, particularly those tightened by national and European regulations, as requirements for noise levels in residential buildings. The issue of airborne noise is covered by other standards.
The standard is specifically designed for applications in heating systems and domestic hot water systems where circulation pumps play an important role in maintaining fluid flow.
This section of the standard specifically addresses the noise aspects of these circulation pumps. Provides a noise test code focusing on vibration acoustics to measure both structure-borne and fluid-borne noise.
To obtain reproducible results from measurements, it is important to use equipment that complies with or corresponds to all specifications and installation recommendations given herein.
