The standard was first published in 1999 and provides a universally recognized method for measuring the viscosity of industrial cellulose nitrate, commonly known as nitrocellulose. This substance is a key ingredient in various surface coatings and printing inks. The standard is specifically designed for solutions where the nitrogen content of the nitrocellulose varies between 10.7% and 12.6% by mass . Crucially, ISO 14446 does not just stop at measurement. It also establishes a classification system (detailed in Annex A of the document) for these solutions based on the viscosity results obtained. The primary goal is to create "standard" types, preventing discrepancies in classification that often arise from laboratories using different measurement techniques or various types of solvents. iso 146446 pdf
: The core standard for air cleanliness classification (ISO Classes 1–9).
The classification limit of particles (e.g., ISO Class 5) that a cleanroom must not exceed.
: These newer sections focus on energy efficiency in cleanrooms and the assessment of particle deposition rates on surfaces. Implementing the requirements of ISO 14644-6 PDF offers
ISO 14644-6 is a master compendium that aggregates and verifies definitions across multiple sections of the cleanroom standard family. Instead of hunting through individual parts for specific technical nuances, professionals utilize this document to ensure standard nomenclature. The Structural Architecture of ISO 14644
Cleanrooms are notorious energy hogs. Because they require massive volumes of filtered, conditioned air to eliminate microscopic particles, a typical cleanroom consumes up to than a standard commercial office space.
The standard is not static. ISO/TC 209, the technical committee responsible for its development, regularly reviews and updates parts to keep pace with technological advancements and industry needs. Recent trends include: Can’t copy the link right now
Airflow that moves in a single, uniform direction. 3. Training and Auditing
: This section requires facilities to develop a monitoring plan based on risk assessment to prove they consistently meet cleanliness standards.

is a series of international standards for cleanrooms and controlled environments, which you can find through the ISO Official Publication Portal .
This is the foundational document. It classifies cleanrooms based on the concentration of airborne particles (0.1 m) per cubic meter of air.
