DIN EN 1151-2-2006 泵.旋转动力泵.家用热水装置和供热装置用的额定功率输入不超过200W的循环泵.第2部分:测量结构和流体导声的噪音试验编码（声振捣）
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; English
This part of EN 1151 specifies a test code for the vibro-acoustic charaterisation of circulation pumps as defined in EN 1151-1 , and is limited to circulation pumps with threaded connections of 3/2 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.
