This European Standard is to be seen in close connection with draft standard DIN IEC 61 (Sec) 694 (Classification VDE 0700 Part 51) relating to safety requirements for the electric part of glandless circulators. In addition to the legal units of measurement, this standard also

9、uses the unit “inch”. It should, however, be noted that the Gesetz ber Einheiten im Messwesen (German Law on units in metrology) prohibits the use of these units for official and commercial purposes in Germany. The indication of this unit solely serves to facilitate the communication with those coun

10、tries where this unit is used (import-export business). The European Standards referred to in Clause 2 and in the Bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. Where the International Standards referred to are not also DIN ISO St

11、andards with the same number, there are no national standards available. Amendments This standard differs from DIN EN 1151-2:2006-11 and DIN EN 1151-2 Corrigendum 1:2008-06 as follows: a) the scope has been extended to include frequency controlled glandless circulators; b) Clause 4 “Symbols and unit

31、N 16644:2015-04EN 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

32、especially in residential housing, tightened by national and European regulations. The issue of airborne noise is covered by other standards. DIN EN 16644:2015-04EN 16644:2014(E)6 1 Scope This European Standard specifies a test code for the vibro-acoustic characterization of glandless circulators wi

33、th 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

34、 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 pr

35、essure 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.
