DIN Certification: Quality & Reliability of your Laser Cartridges

Standard established by the “Deutsches Institut fur Normung” [German Standards Institute], regulating the quality and reliability of recycling colour and monochrome laser cartridges.

This standard defines the features of monochrome (33870-1) and colour (33870-2) laser cartridges, as well as the tests and conditions for their remanufacturing.

It also takes into account yield and environmental and sustainable aspects of remanufactured cartridges.
