Pumps - Rotodynamic pumps - Glandless circulators having a rated power input not exceeding 200 W for heating installations and domestic hot water installations - Noise test code (vibro-acoustics) for measuring structure- and fluid-borne noise

This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators
with pump housing having a rated power input P1 ≤ 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.

EN 16644:2014 (E) 5 Introduction This document covers the measurement of fluid and structure-borne noise as induced by small glandless circulators having a rated input of ≤ 200 W. It has been prepared in response to the need of having uniform procedures as requirements for noise levels especially in residential housing, tightened by national and European regulations. The issue of airborne noise is covered by other standards. SIST EN 16644:2015



EN 16644:2014 (E) 6 1 Scope This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators with pump housing having a rated power input P1 ≤ 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. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
