Cleanroom compatibility tested
CLEAN Advanced and CLEAN Supreme
have been tested and assessed the
Fraunhofer Institute Stuttgart (Germany)
with respect to
–
cleanroom compatibility for cleanrooms
(particle emission behaviour the
luminaires) and
–
cleanliness compatibility (disinfectability,
electrostatic behaviour and chemical
resistance).
The particles inside this test chamber are
monitored and recorded appropriately. These are defined in
the following standards and codes practice,

assessments and parameters were included
in the tests conducted the Fraunhofer
