As instruments and equipment are introduced and particulates rise an as built cleanroom becomes an at rest cleanroom. 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.
