Tab. A
(1)
Reference conditions: Ambient temperature 20°C - Gas temperature 15°C - Barometric pressure 1,013 mbar - Altitude 0 m a.s.l.
(2)
Pressure at test point with zero pressure in combustion chamber and at maximum burner output.
(3)
Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler and at maximum rated output. The sound
power is measured with the “Free Field” method, as per EN 15036, and according to an accurate “Accuracy: Category 3” measurement, as de-
scribed in EN ISO 3746.
