Measuring­surface Sound­pressure Level; Measuring­surface Sound­pressure Level For Bevel Gear Units (K; Weights - Siemens FLENDER K1N Assembly And Operating Instructions Manual

1.2 Measuring­surface sound­pressure level
The gear unit has a measuring­surface sound­pressure level at a distance of 1 m, which can be found in
tables 1 and 2.
The measurement is carried out to DIN EN ISO 9614 Part 2, using the sound­intensity method.
The workplace of the operating personnel is defined as the area on the measuring­surface at a 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 n
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.
