Particle emission (VDI 2083 part 9.1)
| frequency (sinusoidal oscillation): 50 Hz oscillation velocity 4 µm/s oscillation acceleration: 3 mm/s² oscillation of the system: 0,03 µm | ISO 14644-1 | / | ISO Class 4 (mit Einschränkung/ with limitation) | US FED 209E | / | US Class - | Comment 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 systems cannot be used in some cases. | Comment 2: | / | Cleanrooms with a horizontal displacement flow form an exception to this. | Comment 3: | / | Extra care needs to be taken while installing the ceiling tiles to avoid damage to their coated surfaces as this might have negative impact on the particle emission behavior. | Comment 4: | / | Accessories used to install the ceiling system can influence the cleanroom suitability as well. Therefor particle emission behavior should be reassessed in the respective assembly situation. | | certificate
