Chemical Emissions:
Air emissions testing is performed in accordance with “Test method for the determination of emissions from
hardcopy devices with respect to awarding the environmental label for office devices with printing function
according to RAL-UZ 122,” BAM April 2006.
The exposure scenario (concentration) is based on a generic office model; consisting of two hours of printing
in an eight-hour day in a 32 cubic meter room with a ventilation rate of 0.72 air changes per hour.
Note: Tests are conducted using HP printing supplies. Results with other than HP supplies may differ.
