Overview

This European Standard 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. 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". 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. This standard contains the German version of EN 16644:2014 which has been prepared by Technical Committee CEN/TC 197 "Pumps" at the European Committee for Standardization (CEN). This document supersedes EN 1151-2:2006. This European Standard replaces EN 1151-2:2006 as a result of the withdrawal of EN 1151-1 and the issuing of the EN 16297 series as its replacement and is expanded to include cooling systems. 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 units" has been included; c) 6.2 "Operating parameters" has been revised. The national interests during the preparation are represented by Committee NA 060-11-01 AA "Kreiselpumpen" ("Centrifugal pumps") of Technical Section "Pumps" of the Standards Committee Mechanical Engineering (NAM) at DIN. Representatives of the manufacturers and users of pumps, and of the employers' liability insurance associations are involved in the preparation.
