What 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 capabilities of induction units for air distribution systems.
BS 4954-2 is the second part of the BS 4954 series, which provides standardized ratings to induction units based on the test methods.
BS 4954-2 deals with methods of acoustic testing and rating of induction units, defined in Part 1 of BS 4954-2, for:
- Sound power emission
- Terminal attenuation
Who is BS 4954-2 - Acoustic testing and rating of induction units for?
BS 4954-2 on acoustic testing and rating of induction units is relevant to:
- Manufacturers of components of ventilation and air conditioning systems
- Manufacturers of induction units
- Quality control and testing personnel
- Mechanical engineers
- Product designers
Why should you use BS 4954-2 - Acoustic testing and rating of induction units?
It is vital that the acoustic disturbances of induction units be assessed in order to minimize the high noise pollution made by induction units, such as induction motors, 3-phase induction motors, induction ovens etc.
In this regard, BS 4954-2 provides best industry test methods to measure acoustical disturbances in induction units, and provides ratings based on the generated noise test, and static insertion loss test. Moreover, instrumentation for measuring acoustical disturbances in induction units is also covered by BS 4954-2.
Thus, if you are a manufacturer of induction units, by adopting BS 4954-2-compliant testing and rating of induction units, you can determine whether your products are fit for its intended use. As a result, you can identify and correct the source of acoustic noise in induction units such that their operational and functional efficiency remains uncompromised.
