Originally Federal Standard 209E defined a class 10,000 clean room based on the particle counts given below. A class 10,000 clean room is currently defined as an ISO 7 clean room using the ISO standard 146441.
Clas | maximum particles/m³ | ||||
ISO-146441 | Federal Standard 209E | ≥0.3 µm | ≥0.5 µm | ≥1 µm | ≥5 µm |

ISO-7 | 10,000 | 83,200 | 2,930 |
The clean room using the same above particle counts.
The Physics clean room is about 200
