The need for a single standard for cleanroom classification and testing was long felt.

ISO covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this isi is specified and accomplished exclusively in terms of concentration of airborne particulates. Part 2 specifies requirements for periodic testing of a cleanroom or clean zone to prove its continued compliance with ISO for the designated classification of airborne particulate cleanliness.

It also specifies 41644-1:1999 for the monitoring of a cleanroom or clean zone installation to provide evidence of its continued compliance with ISO for the designated classification of airborne particulate cleanliness. 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.


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 purchaserssuppliersand designers of cleanroom installations. ISO provides the basic requirements for operating and maintaining cleanrooms and associated controlled environments.

ISO 14644-1:1999 Certification Definition

This standard kso requirements that are basic to the operation of all cleanrooms, regardless of the application. This part was published as an International Standard in This part is an important document for any contamination control professional. This part of ISO 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. This part of ISO covers the classification of airborne molecular contamination AMC in cleanrooms and associated controlled environments, in terms of airborne concentrations of specific chemical substances individual, group or category and provides a protocol to include test methodsanalysis and time-weighted factors within the specification for classification. This document became a Standard in This ISO document describes the classification of the particle contamination levels on solid surfaces in cleanrooms and associated controlled environments applications.


Recommendations on testing and measuring methods as well as information about surface characteristics are given in informative annexes. It is currently a Committee Draft and is not yet available as a Standard. From Wikipedia, the free encyclopedia.
