distance of 1 , which can be found in tables 7 to 1. The measurement is carried out to DIN EN ISO 9 Part 2, using the soundintensity method. The workplace of the operating personnel is defined as the area on the measuringsurface at distance of 1 metre in the vicinity of which persons may be present. The soundpressure level applies to the warmedup gear unit at input speed 1 and output power 2 stated on the rating plate, as measurement obtained on the Siemens test bench. If several figures are given, the highest speed and power values apply. The measuringsurface soundpressure level includes addon lubrication units, if applicable. With outgoing and incoming pipes, the interfaces are the flanges. The soundpressure levels stated in the table were obtained by statistical calculation by our Quality Control Dept. The gear unit can be statistically expected to comply with these soundpressure levels. 1.1.2.1 Measuringsurface soundpressure level for bevelhelical gear units (..) with fan Table 7: Measuringsurface soundpressure level pA in dB() for bevelhelical gear units with fan Type iNn1 1/minGearunit size 1 1 1 1 1 1 1 1 1 1 2 2 2 B2 3 7 8 8 8 - - - - - - - - - - - - - - - - - - . 1 6 7 7 7 7 8 8 8 8 8 8 8 9 9 9 - - - - - - - . 1 6 7 7 7 7 7 7 8 8 8 8 8 8 8 9 - - - - - 8 7 6 6 6 6 7 7 7 7 7 7 7 7 8 8 8 8 - - - - 9 3 7 8 8 8 8 9 - - - - - - - - - - - - - - - - . 1 6 6 7 7 7 7 7 8 8 8 8 8 8 8 8 9 - - - - - - . 1 6 6 6 6 7 7 7 7 7 7 8 8 8 8 8 8 8 - - - - 1 7 6 6 6 6 6 6 7 7 7 7 7 7 7 7 8 - - - - 1 3 7 7 8 8 8 8 9 9 9 - - - - - - - - - - - - - . 1 6 6 6 7 7 7 7 7 8 8 8 8 8 8 8 9 - - - - - - . 1 6 6 6 6 7 7 7 7 7 7 8 8 8 8 8 8 - - - - 2.4 7 6 6 6 6 6 6 7 7 7 7 7 7 7 7 - - - - B3.5 3 - - 8 8 8 8 9 9 9 - - - - - - - - - - - - - . 1 - - 6 7 7 7 7 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 . 1 - - 6 6 6 6 7 7 7 7 7 7 8 8 8 8 8 8 8 8 8 8 3.5 7 - - 6 6 6 6 6 7 7 7 7 7 7 7 7 7 7 7 8 8 3.5 3 - - 8 8 8 8 8 8 9 9 9 9 - - - - - - - - - - . 1 - - 6 6 7
