Vibration (optional)
The vibration level should be measured as described in ANSI/NSF Standard 49:2012.
Note: The vibration meter should have a range of 20-20,000 Hz, and have an
output in displacement.
1.
Vibration level should be recorded from a single point, on the geometric center
of the work surface.
2.
Take a background reading with the cabinet blower off at the test point.
3.
Start the cabinet blower, and take a vibration reading.
Acceptance
Vibration should be less than 0.0002 inches displacement when the cabinet is new.
UV intensity (optional)
Note: The UV radiometer should measure light at a wavelength of 254nm.
1.
UV intensity should be recorded from a single point, on the geometric center of
the work surface.
2.
Take a background reading with the cabinet blower off at the test point.
3.
Close the sash, turn on the UV light, and let it warm up for at least 5 minutes.
Acceptance
The UV intensity should be at least 200 uW-cm
