Understanding the Cornerstone Cleanroom Standards: ISO 14644-1 and 14644-2


ISO 14644-1 and 14644-2 are the cornerstone international cleanroom standards, essential for all contamination control professionals. This course covers the nuts and bolts of ISO 14644-1:2015, Cleanrooms and associated controlled environments—Part 1: Classification of air cleanliness by particle concentration, and ISO 14644-2: 2015, Cleanrooms and associated controlled environments—Part 2: Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration.

This full-day course also includes: (1) a brief overview of the entire ISO 14644 series to help you become familiar with the breadth of this essential International Standards Series and (2) critical insights into the 2015 revision to these standards, including changes in the revised Standards, how they impact your cleanroom operations, and the rationale of the documents.

Learn directly from the Secretariat of ISO Technical Committee 209, the committee that writes these essential standards.

Please bring a calculator as it will be needed for a course exercise.
