3.0 APPLICABLE STANDARDS

AIRFLOWThe test set up was in accordance with Standard BS 848

ACOUSTICSAustralian Standard 1217.2-1985. "Acoustic - Determination of Sound Power Levels of Noise Sources Part 2 - Precision Methods for Broad-Band Sources in Reverberation Rooms".

4.0 TEST SET UP AND PROCEDURE

The Units under test were set up in the Vipac Air Distribution Test Chambers (Reverberation Rooms 1 and 2) and connected to a quiet air supply.

The units were supplied with ambient temperature air at the specified airflows. The environmental test conditions in the reverberation chamber varied for each test within the following ranges:

Test Air Temperature 17 degrees C ± 2.0 degree C

Room Air Temperature 19 degrees C ± 2.0 degree C

Barometric Pressure 1050 millibar ± 5 millibar

Relative Humidity 50 + 10%

Air flow rates were measured using orifice plates located upstream of the fan under test. Static pressure drop was recorded using 4 manifolded pressure tappings located upstream of the fan under test. Figure 10 shows an indicative schematic of the laboratory set up.

Testing commenced with a relatively high resistance upstream of the fan under test. The various fan flow conditions were achieved by varying of the resistance upstream of the fan, which was achieved by adjustment of a secondary fan.

Radiated noise was measured in Reverberation Room 1 and Discharge noise was measured in Reverberation Room 2.

Following calibration checks, sound pressure levels were measured and converted to sound power levels using the comparison method of AS1217.2 (ie. using a reference sound source of known Sound Power to determine room correction).
