Acoustics; Laboratory tests on noise emission from appliances and equipment used in water supply installations; Part 1 : Method of measurement

This document establishes a standardized framework for the laboratory assessment of acoustic emissions generated by devices and equipment utilized in water supply systems. It specifically details the methodologies required to measure sound levels produced by these components under controlled testing conditions. The content focuses on defining precise procedures for instrumentation setup, environmental requirements, and data acquisition techniques to ensure consistency across different testing environments. By outlining specific measurement protocols, the text aims to provide a uniform approach for evaluating noise characteristics of water supply apparatus. It addresses various operational scenarios to facilitate accurate comparisons between different products and designs. The procedures described are intended for use in quality control processes and research applications where understanding acoustic output is critical for system design and regulatory compliance. This guide forms the foundational reference for conducting reproducible sound measurements without specifying individual brand performance or making subjective assessments of the equipment tested.
