ISO 14644-1 Clean Rooms and Related Controlled Environments, Part 1: Classification of Air Cleanliness by Particulate Concentration

EUROLAB laboratory provides testing and compliance services within the scope of ISO 14644-1 standard. This part of ISO 14644 specifies the classification of air cleanliness in terms of the concentration of airborne particles in clean rooms and clean areas.

ISO 14644-1 Clean Rooms and Related Controlled Environments, Part 1: Classification of Air Cleanliness by Particulate Concentration

For classification purposes only populations of particles with cumulative distributions based on threshold (lower limit) particle sizes ranging from 0,1 µm to 5 µm are considered.

The use of light scattering (discrete) airborne particle counters (LSAPC) provides the basis for determining the concentration of airborne particles greater than or equal to the specified sizes at designated sampling locations.

This part of ISO 14644 does not provide classification for populations of particles that fall outside the specified subthreshold particle size range, such as 0,1 µm to 5 µm.

Concentrations of ultrafine particles (particles smaller than 0,1 µm) are handled in ISO 14644-12, which specifies air cleanliness with nanoscale particles, while an M descriptor can be used to quantify populations of macroparticles (particles). This part of ISO 14644 cannot be used to characterize the physical, chemical, radiological, living or other nature of airborne particles.
