This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators with pump housing having a rated power input P<\/i> 1<\/sub> \u2264 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.<\/p>\n

This European Standard applies to glandless circulators, which are manufactured after the date of issue of this European Standard.<\/p>\n

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.<\/p>\n
