Measurement of Fine and Ultrafine Particles from Office Devices during Printing in order to Develop a Test Method for the Blue Angel Ecolabel for Office-Based Printing Devices

The research project on which this report is based focuses on the measurement of particulate emissions in the area of fine and ultrafine particles from laser printing devices. Against the backdrop of a public debate about possible hazards related to these emissions, UBA has commissioned BAM to develop a measurement method for these emissions, to expand the existing awarding criteria for the "Blue Angel" ecolabel by the aspect of particle emissions and to physically and chemically analyse particulate emissions. The resulting awarding criteria will be submitted to RAL later this year. Emission characteristics of laser printing devices, conclusions on awarding criteria and interim results of the project were discussed in three sessions of a project-related expert group.
