The series operates as a modular collection of parts, each addressing a specific aspect of cleanroom technology. The most fundamental part, , defines cleanroom classes (ISO Class 1 through ISO Class 9) based on the concentration of airborne particles permitted per cubic meter of air. This classification system provides the foundation for all other parts of the standard.

I notice you're asking for a of ISO 14644-3:2019 (there is no 2021 version of this specific part; the latest is 2019, with a 2021 amendment possibly to another part like ISO 14644-1 or -2).

All guidance concerning the classification of air cleanliness by particle concentration was removed from this part and consolidated into ISO 14644-1. iso 146443pdf 2021

The 2019 revision was significant, focusing on streamlining procedures and aligning with other ISO 14644 parts. Key changes include:
