ISO 14644

ISO 14644 Standards were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. The need for a single standard for cleanroom classification and testing was long felt. After ANSI and IEST petitioned to ISO for new standards, the first document of ISO 14644 was published in 1999, ISO 14644-1.

In 2000, ISO 14644-2 was published, which began the process of FED-STD-209E being canceled. On November 29, 2001, the document was canceled and superseded by ISO 14644-1 and ISO 14644-2.

ISO 14644 is now composed of

• ISO 14644-1: Classification of air cleanliness
• ISO/DIS 14644-1.2(2014): Classification of air cleanliness by particle concentration
• ISO 14644-2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1
• ISO/DIS 14644-2.2(2014):Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration
• ISO 14644-3: Test Methods
• ISO 14644-4: Design, Construction, and Start-up
• ISO 14644-5: Operations
• ISO 14644-6: Vocabulary
• ISO 14644-7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments
• ISO 14644-8: Classification of airborne molecular contamination
• ISO 14644-9: Classification of surface particle cleanliness
• ISO 14644-10: Classification of Surface Cleanliness by Chemical Concentration
• ISO 14644-12: Classification of Air Cleanliness by Nanoscale Particle Concentration

Part 1: Classification of air cleanliness

ISO 14644-1 covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. The document was submitted as an American National Standard and has been adopted as ANSI/IEST/ISO 14644-1:1999 in the United States, following the cancellation of FED-STD-209E.

Part 2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1

Part 2 specifies requirements for periodic testing of a cleanroom or clean zone to prove its continued compliance with ISO 14644-1 for the designated classification of airborne particulate cleanliness. It also specifies requirements for the monitoring of a cleanroom or clean zone (installation) to provide evidence of its continued compliance with ISO 14644-1 for the designated classification of airborne particulate cleanliness.. It became an International Standard following the cancellation of FED-STD-209E. In the United States in 2000 it was adopted as ANSI/IEST/ISO 14644-2:2000.

Part 3: Test Methods

This part specifies test methods for designated classification of airborne particulate cleanliness and for characterizing the performance of cleanrooms and clean zones. These test methods are specified in the document for two different types of cleanrooms and clean zones; unidirectional flow and nonunidirectional flow.

The most important objectives of this highly referenced document are to provide an internationally common basis of measurement and evaluation of cleanrooms and, at the same time, not to prevent the introduction of new technologies."ISO 14644-3 Scope". IEST. 2007-12-03. Retrieved 2008-01-17.</ref>

Part 4: Design, construction and start-up

This part specifies requirements for the design and construction of cleanroom and clean air devices, as well as requirements for start-up and qualification, but does not prescribe specific technological nor contractual means to meet the requirements. This document is intended for purchasers, suppliers, and designers of cleanroom installations. It was submitted as an American National Standard in 2001.
