This European Standard applies to heat generators according prEN 15036-1, which are connected to chimneys/ducts which discharge duct into the open air, except for type B and type B11 BS appliances fitted with atmospheric burners. 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 the indoor air can also be measured in accordance with this Standard. Boilers supplied with combined air inlet and exhaust terminal configuration where ducts are within an external wall can be measured according Annex D on the choice of the manufacturer. Except for low level discharge boilers or room sealed boilers which are supplied complete with their own integral flue terminal arrangement, the flow of combustion air should not influence the measurement of the flue gas noise emission. The possibility likewise exists for heat generators operating independently of the indoor air to be measured using the intensity method described in EN ISO 9614-1 and EN ISO 9614-2 by taking the sound power level immediately ahead of the connection of the flue gas (intake air) system. 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. The minimum diameter of the measurement duct is 0,06 metres, and the highest permissible average flow speed at the microphone head is 5 metres/second.
