Tab. A
(1)
Reference conditions: Room temperature 20°C - Barometric pressure 1013 mbar – Altitude 0 m above sea level
(2)
Sound pressure measured in manufacturer's combustion laboratory, with burner operating on test boiler and at maximum output. The sound power
is measured using the "Free Field" method, required by the EN 15036 standard, and according to an “Accuracy: Category 3” measurement, as
described in EN ISO 3746.
