This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators with pump housing having a rated power input P 1 ≤ 200W, intended to be used in heating installations, domestic hot water service installations and cooling systems, and is limited to glandless circulators with threaded connections of 11/2 inch. The test code comprises the test rig, the measurement method and the test conditions.
This European Standard applies to glandless circulators, which are manufactured after the date of issue of this European Standard.
The characterization principle is based on measuring the structure-borne and the fluid-borne power transmitted respectively by vibration and pressure fluctuations in the pipe connected to a glandless circulator.
