Acoustics - Laboratory tests on noise emission from appliances and equipment used in water supply installations - Part 2: Mounting and operating conditions for draw-off taps and mixing valve

This technical document outlines laboratory testing methods for determining noise emissions from appliances and equipment within water supply systems, specifically focusing on faucets and mixing valves. It establishes standardized procedures for the installation and operational conditions required during acoustic measurements, ensuring consistency across various testing environments. The specified conditions cover mechanical setup, water pressure parameters, and flow rates necessary to simulate real-world usage scenarios while allowing for precise quantification of sound levels generated by these components. By defining uniform test protocols, the document facilitates comparative evaluation of product performance in the acoustic domain. It serves as a reference for manufacturers, testing laboratories, and regulatory bodies to assess the acoustic behavior of mixing devices under controlled laboratory settings. The content emphasizes reproducibility and accuracy in measurement techniques, ensuring that results obtained from different facilities remain comparable. This approach supports quality assurance processes within the plumbing industry by providing clear guidelines for evaluating noise generation during normal operation.
