4.6 Random Vibration

Non-operating:0.01 g²/Hz at 5 Hz, sloping to 0.02 g²/Hz at 20 Hz, and maintaining 0.02 g²/Hz from 20 Hz to 500 Hz. The area under the PSD curve is 3.13 gRMS. The duration shall be 10 minutes per axis for all three axes on all samples.

4.7 Acoustics

Sound Power: The power supply assembly shall not produce a declared sound power level greater than 3.8 BA. Sound power determination is to be performed at 43C, 50% of rated load, at sea level. This test point is chosen to represent the environment seen inside a typical system at the idle acoustic test condition, with the 43C being derived from the standard ambient assumption of 23C, with 20C added for the temperature

rise within the system (what is typically seen by the inlet fan). The declared sound power level shall be measured according to ISO 7779 and reported according to ISO 9296.

Pure Tones: The power supply assembly shall not produce any prominent discrete tone determined according to ISO 7779, Annex D.

4.8 Ecological Requirements

The following materials must not be used during design and/or manufacturing of this product:

•Cadmium shall not be used in painting or plating.

•Quaternary salt and PCB electrolytic capacitors shall not be used.

•CFC’s or HFC’s shall not be used in the design or manufacturing process.

•Mercury shall not be used.
