1.3.1.5 Noise Level Test
The cabinet was isolated in a noise-controlled environment and a noise level meter was set up at a distance of
30 cm in front of the cabinet and 38 cm above the work surface. With the cabinet running under normal
parameters, the instrument was used to obtain a noise level of the cabinet during normal operation.
Result: dBA
Acceptance: Less than 67 dBA (Based on IEST-RP-CC002.3 Section 6.11)
Result: Pass/ Fail
Disclaimer:
1. This noise test was done in the factory that is susceptible to reflective, reverberant, and background
noise effect. This noise figure may be different than the brochure value that is obtained from anechoic
chamber.
2. If the difference between cabinet and ambient noise was less than 10 dBA, correction chart was used,
which combined with transient ambient noise, may vary the corrected noise level by ± 1.5 dBA.
Testing was performed in accordance with the following IEST (Institute of Environmental Sciences and
Technology) contamination control document: IEST-RP-CC002.3 “Recommended Practice for Unidirectional
Flow Clean Air Devices” Section 6.11.
1.3.1.6 UV Radiation Intensity Test
UV radiation intensity meter was used to obtain light intensity at work surface level within the cabinet.
Readings were taken along the front to back centerline within the interior work area: All units are µW/cm
2
Average reading: µW/cm
2
Acceptance: UV Radiation intensity inside the cabinet should not be less than 40 µW/cm
2
UV Radiation intensity outside the cabinet with all windows closed must be zero
Results: Pass / Fail
Note: The UV radiation intensity test is tested with shelf unassembled. The
shelf is designed for user who desires to obtain higher intensity, i.e. item to
be disinfected is to be placed on the shelf.
