Definitions
According to http://www.set3.com/standards.html
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-6 | 1,000 | 102,000 | 35,200 | 8,320 | 293 |
ISO-7 | 10,000 | 352,000 | 83,200 | 2,930 |
The clean room using the same above particle counts.
PCR specific
The Physics clean room is about 200

The average and SD are calculated by taking 5 minute measurements 5 times.

Since 0.3 µm measurements are not a required measurement for Class 10,000, they are not included here.
