Tests & results

Particle emission (ISO 14644-1, -14)

Particle emission (ISO 14644-1, -14)
Test parameter(s)	Air Cleanliness Class
Structure-borne noise = approx. 50 Hz	1
Overall result	1

It must be pointed out, that according to ISO 14644-1 cleanrooms classes 1 to 5 have a high filter occupancy, with the result that large-surface ceiling/lighting systems cannot be used in some cases. Cleanrooms with a horizontal displacement flow form an exception to this.

The test result may be influenced by the surrounding lighting system, in particular the material pairing between the light and ceiling frame, as well as other assembly accessories. Particle emission behavior should be re-assessed in the respective assembly situation. The cut edges/back are made of very porous material. Therefore, the use of the test piece in clean/hygienic areas is considered to be critical.

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