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 [math]m^3[/math]

Clas		Counts

ISO-7	10,000		70,400,000	83,200	2,930

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