1.3.2.6 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

Acceptance: UV Radiation intensity inside the cabinet should not be less than 40 μW/cm

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 the shelf unassembled. The shelf is designed for users who
want to obtain higher intensity, i.e. item to be disinfected is to be placed on the shelf.
