Defines cleanliness classes (ISO Class 1 to 9) based on the concentration of particles per cubic meter of air. Part 2: Monitoring for Performance (ISO 14644-2):
This section provides the "how-to" for testing. It covers essential procedures like airflow visualization and HEPA filter validation
is a series of international standards developed by the International Organization for Standardization (ISO). It establishes the classification of air cleanliness by particle concentration, as well as the monitoring and testing methods required to maintain that cleanliness.
The classification relies on the formula relating the maximum allowable particles per cubic meter of air to the particle size. For example, an cleanroom is roughly equivalent to the old "Class 100" standard, meaning it allows no more than 3,520 particles per cubic meter that are 0.5 micrometers or larger.
Here is a breakdown of what the ISO 14644 family covers and why these documents are essential for compliance. What is ISO 14644? ISO 14644 is the international set of standards for cleanrooms and associated controlled environments
: This section requires facilities to develop a monitoring plan based on risk assessment to prove they consistently meet cleanliness standards.
Ongoing observation to check if a system continues to operate within specifications. ISO 14644 Series Overview
The standard dictates the (typically ranging from 0.1 µm to 5 µm) to achieve a given classification.
Airborne particulate classification and specifications for constant operational monitoring.
