CEN/TC 57/WG 6 - Airborne noise emissions

This European Standard applies to heat generators according to EN 15036-1, which are connected to chimneys/ducts which discharge combustion products via a duct into open air.
The data measured according to this European Standard will probably be different from the noise radiated from the end of the chimney.
Readings from forced-draught burners complying with EN 267 or EN 676 are only applicable in practice if they have been taken in conjunction with a boiler. Noise emitted into chimneys/ducts by heat generators operating independently of indoor air can also be measured in accordance with this European Standard.
Boilers supplied with combined air inlet and exhaust terminal configuration where ducts are within an external wall can be measured according to one of the test methods detailed in EN 15036-1.
This European Standard describes the objective procedure for determining sound power levels LW, at the outlet of a heat generator that is emitting broad-band, narrow-band, or tonal continuous sound.
This European Standard is applicable to boilers designed to be connected to a chimney or flue duct with a duct size greater than or equal to 0,06 m and whose mean flue gas flow at the microphone head is less than 5 m/s.
This European Standard only applies for test purposes under laboratory conditions.

This European Standard specifies test methods for airborne noise emissions from heat generators in a test laboratory or at the place of installation.
The test methods described in this European Standard, however, may be used for measuring the airborne noise emissions of the appliances and functions listed below.
This European Standard applies to following appliances regardless of their heat output and the fuel used:
   wall-mounted and floor-standing heating appliances;
   forced-draught burners;
   boilers/forced-draught burner units;
   boilers with freely allocated forced-draught burners;
   pellet burners.
According to this European Standard the manufacturer is allowed to choose an appropriate category of testing for the measured appliance.
This European Standard does not apply to:
   appliances used exclusively for heating drinking-water;
   function of heating drinking-water in so-called combined water-heaters;
   heat generators which work with air as the heat transfer medium;
   electrical heating appliances;
   structure-borne noise;
   sound transmission along the flue gas path.
