Defines particle concentration limits (ISO Class 1 to ISO Class 9).
by particle concentration. This is the most common part used to define "Class 1" through "Class 9" cleanrooms. ISO 14644-2 : Provides the requirements for monitoring and testing to provide evidence of ongoing cleanroom performance. ISO 14644-3 : Details the test methods used to characterize cleanrooms. ISO 14644-4 & 5 : Cover the design, construction, and operation of cleanroom facilities. American Cleanroom Systems How to Access the PDF iso 146446 pdf
Relying on "free" PDFs found via search engines can be risky for critical compliance work. These documents may be outdated, scanned poorly, or altered. For GMP (Good Manufacturing Practice) compliance, it is always recommended to possess a licensed copy of the standard.

If you did not mean the standard itself but a specific academic paper discussing it, a highly cited paper regarding the changes in this standard is often titled along the lines of:
Specifications for testing and monitoring to prove continued compliance. ISO 14644-4:2001 : Design, construction, and start-up. How to Acquire the ISO 14644-6 PDF
Originally, provided a compendium of terms and definitions used across the ISO 14644 family. By centralising this terminology, the standard ensured that engineers, auditors, and facility managers across the globe used the same language when discussing particle concentration, airflow, and contamination control.
