Overall result

4

It should be noted that cleanrooms of class 1 to 5 according to ISO 14644-1 have a higher filter occupancy, which may restrict the use of flat ceiling systems. Cleanrooms with a horizontal displacement flow form an exception to this. The test result may be affected by the surrounding ceiling system, in particular the material pairing between luminaire frame and ceiling system, as well as other mounting accessories. Particle emission behavior should be reassessed in each assembly situation.

The cut edges/backside consist of very porous material. This is to be considered critical in clean/hygienic areas.

Please note: Transport damages, incorrect installation, aging behavior, corrosion etc. can influence the test result.
