What is BS EN 60704-2-2 - Airborne acoustical noise of fan heaters about? 
BS EN 60704 is a series of British Standards that discusses household and similar appliances and the test code for the determination of airborne acoustical noise emitted.
BS EN 60704-2-2 is one of the parts in the BS EN 60704 series that discusses the determination of airborne acoustical noise of fan heaters.
BS EN 60704-2-2 applies to electric fan heaters, designed for placing on the floor, table or counter, etc. or for wall-mounting.
BS EN 60704-2-2 does not apply to:
- Electric storage room heaters
- Room humidifiers
- Room dehumidifiers
- Air cleaners
- Heaters designed exclusively for industrial purposes. 
Who is BS EN 60704-2-2 - Airborne acoustical noise of fan heaters for? 
BS EN 60704-2-2 on determination of airborne acoustical noise of fan heaters is useful for: 
- Manufacturers of electrical household appliances
- Manufacturers of fan heaters 
- Product design engineers
- Quality control and testing personnel 
Why should you use BS EN 60704-2-2 - Airborne acoustical noise of fan heaters?  
Noise generated by fan heaters is partially of mechanical, electrical, and aerodynamic origin.
The measuring conditions specified in BS EN 60704-2-2 provide for sufficient accuracy in determining the noise emitted and comparing the results of measurements taken by different laboratories, whilst simulating as far as possible the practical use of fan heaters.
It is recommended to consider the determination of noise levels as part of a comprehensive testing procedure covering many aspects of the properties and performance of fan heaters.
BS EN 60704-2-2 provides requirements for the determination of acoustical noise of electric fan heaters along with guidance on measurement of sound pressure levels and calculation of sound pressure and of sound power levels.
This measurement and assessment can be helpful to form a basis for engineering action in the development stages of new pieces of the equipment, or in deciding on means for sound insulation in fan heaters. As a result, if you are a manufacturer of electrical household appliances, you can ensure your products are free from acoustical disturbances, which can ultimately enhance its overall performance and efficiency when in use.
