Liquid pumps and pumps units. Noise test code. Grades 2 and 3 of accuracy Ingestion-build-53008 but does not apply to1 Scope This document specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the airborne noise emission of liquid pumps or pump units (see 4. 1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test. Noise emission characteristics include emission sound pressure levels at specified positions
