While there are many parts to the ISO 14644 series, the most crucial for daily operation and classification are parts 1 and 2. 1. ISO 14644-1: Classification of Air Cleanliness
In the highly specialized world of cleanrooms and controlled environments, precise communication is crucial. Misinterpreting a term related to airborne particulate cleanliness, microbial contamination, or HEPA filter efficiency can result in product failure, regulatory non-compliance, or significant financial losses.
Definitions of basic concepts related to cleanroom air and surfaces.
Necessary for international trade and meeting ISO Standards for quality management.

Would you like to know more about cleanrooms or the ISO 14644 standard?
: This is the most widely cited part. It establishes the "ISO Classes" (Class 1 to Class 9) based on the concentration of airborne particles per cubic metre of air.
The primary function of ISO 14644-1 (the first part of the standard) is to classify cleanrooms based on the concentration of airborne particles.
The standard is not just a technical document; it is a critical tool for risk management, quality assurance, and operational excellence. While there are many parts to the ISO
To obtain the official and current ISO 14644 PDF, you must purchase it from an authorized source. Here are your options:
The ISO 14644 series is divided into multiple parts. If you require the general PDF outlining basic classifications, you likely need Part 1.
For a comprehensive approach to air cleanliness classification and testing, consider pairing this with the .
There is no ISO 146446.
It ensures that a term like "particle" or "cleanroom" means the same thing to a designer in Germany and a user in Japan.
Strictly defines the particle concentration in the air [5.5].
Outlines requirements for a monitoring plan based on risk assessment.
This is the primary document used globally to classify cleanroom cleanliness (e.g., ISO Class 5, ISO Class 7). It replaced the older Federal Standard 209E (which defined classes like "Class 100" or "Class 1000"). To access the PDF of ISO 14644-6, you
