Methods for testing and rating induction units for air distribution systems - Acoustic testing and rating Ingestion-build-61878 upon its filtration rating andWhat is BS 4954 2 Acoustic testing and rating of induction units about? Acoustical testing of a product refers to the evaluation of the vibrations, mechanical impedance and other noises which a product emits while in use. BS 4954 is a European Standard that discusses methods for the evaluation of air disturbances in induction units. The main objective of the BS 4954 series is to provide the best industry methods that demonstrate the performance
