Small numbers refer to ISO 14644-1 standards, which specify the decimal logarithm of the number of particles 0.1 μm or larger permitted per m 3 of air. So, for example, an ISO class 5 cleanroom has at most 10 5 particles/m 3. Both FS 209E and ISO 14644-1 assume log-log relationships between particle size and particle concentration.
The need for a single standard for cleanroom classification and testing was long felt. After ANSI and IEST petitioned to ISO for new standards, the first document of ISO 14644 was published in 1999, ISO 14644-1. [1] In 2000, ISO 14644-2 was published, which began the process of FED-STD-209E being canceled.
FED-STD-209 E Airborne Particulate Cleanliness Classes in Cleanrooms and Cleanzones was a federal standard concerning classification of air cleanliness, intended for use in environments like cleanrooms. The standard based its classifications on the measurement of airborne particles. [1]
ISO 14698-1 was first written in 2003. ISO 14698-1 describes the principles and basic methodology for a formal system to assess and control biocontamination, where cleanroom technology is applied, in order that biocontamination in zones at risk can be monitored in a reproducible way and appropriate control measures can be selected.

Cleanroom suitability describes the suitability of a machine, operating utility, material, etc. for use in a cleanroom, where air cleanliness and other parameters are controlled by way of technical regulations in accordance with ISO 14644. [1] Cleanroom suitability is a subdomain of cleanliness suitability and primarily describes the particle ...
