Defines the maximum allowable concentration of particles per cubic meter of air.
Since the standard is withdrawn, it cannot be purchased as an "active" standard from official bodies. However, there are still a few avenues to find the content:
This feature is written for facility managers, engineers, quality assurance professionals, and regulatory compliance officers in industries such as pharmaceuticals, biotechnology, aerospace, medical devices, and electronics manufacturing.
The ISO 14644 series now integrates essential definitions within each technical part. For example, classification terms are defined in ISO 14644-1:2015, and test method terms are in ISO 14644-3:2019. For general cleanroom terminology, refer to the most recent active parts of the series.

- Details the testing techniques to confirm performance.
Because of these benefits, the definitions from ISO 14644‑6 continue to be relevant, even though the standard itself has been withdrawn. Anyone who refers to an active part of ISO 14644 (e.g., ISO 14644‑1:2015) will find that the terms used in that part are defined within it. However, for a comprehensive, cross‑part glossary, a copy of ISO 14644‑6 remains a valuable tool.
The ISO 14644 series currently consists of more than a dozen parts, each addressing a specific aspect of cleanroom technology. Understanding where ISO 14644‑6 fits among them is helpful:
While ISO 14644-1 handles classification and ISO 14644-2 covers monitoring, acts as the crucial vocabulary and methodology backbone for the entire series.
Instead of searching for a single vocabulary PDF, ensure you are referencing the latest edition of the specific ISO 14644 part relevant to your immediate task, where you will find the current and applicable definitions.

This "vocabulary" standard was a cross-referenced compendium, uniting definitions from parts 1 through 9 of ISO 14644 and parts 1 and 2 of ISO 14698. Each definition was followed by the standard designation and the specific section where it was used, and it featured an index for easy look-up.
The condition of the air in a cleanroom, expressed in terms of the concentration of airborne particles per unit volume of air.
No. ISO 14644‑6 was published only once and has not been revised. The ISO/TC 209 committee has not announced plans to republish a vocabulary part under the number 14644‑6. Instead, the committee may prefer to keep definitions within the technical parts.
