ISO 14644-6 is the international standard titled "Cleanrooms and associated controlled environments — Part 6: Vocabulary". It serves as a unified dictionary for the technical terms and definitions used across the entire ISO 14644 series of cleanroom standards. Core Purpose and Scope
The primary function of ISO 14644-6 is to ensure global consistency in communication. By providing a single source for definitions, it prevents misunderstandings between designers, operators, and auditors in highly regulated industries such as aerospace, microelectronics, pharmaceuticals, and healthcare.
Standardization: It harmonizes terms used in other parts of the series, such as classification (Part 1), monitoring (Part 2), and operations (Part 5).
Target Audience: It is intended for engineers, quality control specialists, and facility managers who need precise language to describe air cleanliness levels, contamination control, and environmental parameters. Status and Availability
Withdrawal Status: Officially, ISO 14644-6:2007 was withdrawn and discontinued by the International Organization for Standardization (ISO).
Integration: The content of Part 6 (Vocabulary) has largely been redistributed or integrated directly into the specific standards where those terms apply, or into general ISO terminology databases, to streamline the documentation process.
National Equivalents: In some regions, national versions of this document may still be archived for reference, such as TCVN 8664-6:2011 in Vietnam. Key Definitions Traditionally Covered
While the document itself is no longer a standalone active ISO standard, the definitions it standardized remain critical to cleanroom operations:
Cleanroom: A room where the concentration of airborne particles is controlled and minimized.
ISO Classification: The numerical ranking (ISO Class 1 through 9) that defines the maximum allowable particle concentration.
Contamination Control: The activities used to control the levels of hazardous substances or particles.
At-Rest vs. Operational: Definitions for the occupancy states of a cleanroom during testing and certification. Where to Find Information Now iso 14644-6 pdf
Since ISO 14644-6 is withdrawn, you should refer to the "Terms and Definitions" section (usually Section 3) of the active active standards for the most current vocabulary:
ISO 14644-1:2015: For terms related to particle concentration and classification.
ISO 14644-2:2015: For terms related to monitoring and testing.
ISO 14644-5:2025: For terms related to the latest operational and contamination control norms.
You can purchase active standards or view summaries on the official ISO website or through authorized distributors like Lighthouse Worldwide Solutions. ISO14644 Cleanroom Guide
