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
Particulates – also known as atmospheric aerosol particles, atmospheric particulate matter, particulate matter (PM) or suspended particulate matter (SPM) – are microscopic particles of solid or liquid matter suspended in the air. The ter ...

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.
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

Part 5: Operations
ISO 14644-5 provides the basic requirements for operating and maintaining cleanrooms and associated controlled environments. This standard addresses requirements that are basic to the operation of all cleanrooms, regardless of the application. Topics include:
*Operational systems that must be in place
*Selection and use of appropriate cleanroom garments

Part 7: Separative devices (clean air hoods, gloveboxes, isolators and minienvironments)
This part of ISO 14644 specifies the minimum requirements for the design, construction, installation, testing and approval of separative devices in those respects where they differ from cleanrooms as described in Parts 4 and 5. Separative devices range from open to closed systems.
The limitations are:
*Application-specific requirements are not addressed.
*User requirements are as agreed by customer and supplier.
*Specific processes to be accommodated in the separative device installation are not specified.
*Fire, safety and other regulatory matters are not considered specifically; the appropriate national and local requirements shall be respected.
*Full-suits are not within the scope of this standard.
This part was published as an International Standard in 2004. The document was submitted as an American National Standard and has been adopted as ANSI/IEST/ISO 14644-7:2004.
