For those new to cleanrooms, take a look at our basic concept of a cleanroom video. 2020-11-30 ISO 14644 Standards were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. As cleanrooms became more sophisticated, the need for wider ranging standards was recognized. The need for a single standard for cleanroom classification and testing was long felt.

13 Nov 2014 As part of the ISO periodic review cycle, ISO 14644-1, Cleanrooms and associated controlled environments — Part 1: Classification of air 

The revised ISO 14644-1:2015 has set new cleanroom classification and monitoring standards for cleanroom managers and manufacturers, causing some questions and confusion.. ISO 14644 expert, Daniele Pandolfi (of Particle Measuring Systems) has written a brief but comprehensive paper that includes: ISO 14644-1:1999, Cleanrooms and associated controlled environments — Part 1: Classification of air cleanliness ISO 14644-2:2000, Cleanrooms and associated controlled environments — Part 2: Specifications for testing and monitoring to prove continued compliance with ISO 14644-1 Simply speaking, for ISO 14644-1 classification, threshold particles of 0.1 microns to 5 microns in size are considered. This standard applies in general to all cleanrooms. Whereas cleanliness standards were once defined by the Federal Standard 209E, they have been replaced and simplified by ISO, with classifications 1 to 9.

This part of ISO 14644 specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones; and separative devices as defined in ISO 14644-7. Only particle populations having cumulative distributions based on threshold (lower limit) particle sizes ranging from 0,1 µm to 5 µm are considered for classification purposes.

As cleanrooms became more sophisticated, the need for wider ranging standards was recognized. ISO-14644-6 Terms, Definitions & Units This document will provide a consistent reference for all terms, definitions and units discussed across all ISO cleanroom standards. ISO-14644-7 Minienvironments & Isolators This document will focus on specialized stand-alone clean spaces including their design, construction, and operations. The recent revision of ISO 14644-1:2015 has introduced several changes for cleanroom classification and monitoring guidelines. This paper highlights the major changes in the new ISO 14644-1 compared to the previous version, as well as the possible impact on the Pharmaceutical EU GMP Annex 1 and FDA Aseptic Processing Guideline. ISO 14644-1:2015: ISO 14644-1:1999: UCL 95%: If the number of sampling locations was between 1 and 10, standard deviation and UCL 95% was calculated and it is this figure that must be within specification for the specific class of clean room.

ISO 14644-3:2019, as the third part of the series of international standards, focuses on the test methods for cleanrooms.

This part of ISO 14644 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. These requirements invoke the test described in ISO 14644-1 for classification of a cleanroom or clean zone.

This part of ISO 14644 specifies the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones; and separative devices as defined in ISO 14644-7.
