Pompat - Pompat rotative dinamike - Pompat e qarkullimit që kanë fuqinë nominale të dërgimit që nuk e kalon 200 W për instalimet e ngrohjes dhe instalimet e ujit të ngrohtë për përdorim shtëpiak - Pjesa 2: Kodi provës së zhurmës (vibro- akuistik) për të matur zhurmën e shfaqur nga struktura dhe fluidi

Pumps - Rotodynamic pumps - Circulation pumps having a rated power input not exceeding 200 W for heating installations and domestic hot water installations - Part 2: Noise test code (vibro-acoustics) for measuring structure- and fluid-borne noise

Scope

This part of EN 1151 specifies a test code for the vibro-acoustic characterisation of circulation pumps as defined in EN 1151-1, and is limited to circulation pumps with threaded connections of 1½ inch. The test code comprises the test rig, the measurement method and the test conditions.
The characterisation 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 circulation pump.
