*Note: Selected tests only performed at 45° setting for the Uni-Vent Adjustable Blade samples.



As indicated above, the Uni-Vent adjustable blade samples were tested for horizontal and 45° throw patterns. The blade settings required to achieve these throw patterns are shown in Figure 1 below.

3.0 TEST CONDITIONS AND APPLICABLE STANDARDS

The units were tested at a range of flow conditions, as shown on the Test Certificates. The test set up was in general accordance with Air Diffusion Council (USA) Equipment Test Code 1062: GRD-84. Measurements were taken in general accordance with the following standards: ACOUSTICS Australian Standard 1217.2-1985. "Acoustic - Determination of Sound Power Levels of Noise Sources Part 2 - Precision Methods for Broad-Band Sources in Reverberation Rooms". AIRFLOW Air Diffusion Council (USA) Equipment Test Code 1062: GRD-84. THROW & STATIC PRESSURE DROP Air Diffusion Council (USA) Equipment Test Code 1062: GRD-84.



4.0 TEST SET UP AND PROCEDURE

Vipac's Reverberation Test Room has a volume of 170m3 has been qualified in accordance with the procedures in AS 1217.2 - 1985 for determination of sound power in octave bands with Centre Frequencies from 125 Hz to 8000 Hz. The units under test were set up in the Air Distribution (Reverberation) Test Chamber and connected to a quiet air supply. The units were supplied with ambient temperature air at the specified airflow. The environmental test conditions in the reverberation chamber varied for each test within the following ranges:

Test Air Temperature 16 degrees C ± 2.0 degree C

Room Air Temperature 18 degrees C ± 2.0 degree C

Barometric Pressure 1045 millibar ± 5 millibar

Relative Humidity 65 + 10% Following calibration checks, sound pressure levels were measured and converted to sound power levels using the comparison method of AS1217.2 - 1985 (ie. using a reference sound source of known Sound Power to determine room correction). Airflow rate was measured using orifice plates. Static pressure drop was recorded using a (Static Pressure) probe and an inclined manometer. Throw was measured using a hotwire type anemometer. Figures 4 to 7 show the test set ups. Figures 8 to 17 show the test units.
