Class 10,000 Cleanroom
Cleanrooms are classified according to the number and size of particles permitted per volume of air. Large numbers like “class 100” or “class 1000” refer to FED-STD-209E, and denote the number of particles of size 0.5 µm or larger permitted per cubic foot of air. Class 10,000 would have <10,000 particles/cubic foot. Minimum of 45 to 60 air changes per hour.
