The latter to cleanrooms where biocontamination may be an issue. The former applies to clean rooms in general see table below. Iso class 1 the cleanest cleanroom is iso 1 used in industries such as life sciences and electronics that require nanotechnology or ultra fine particulate processing.

The cleanroom classification standards fs 209e and iso 14644 1 require specific particle count measurements and calculations to classify the cleanliness level of a cleanroom or clean area.
