Revised clean room standards incorporate best practices for contamination control

Controlling contamination is essential in many manufacturing and research activities. The use of clean rooms, along with strict and stringent processes, makes this possible. The recently revised ISO standards for cleanrooms can help.


Food production, pharmaceuticals, aerospace and automotive manufacturing are just some of the many areas where controlled and classified clean rooms are essential. Clean rooms are zones where contaminants in the air are highly controlled. Without effective control, contamination can wreak havoc on products and processes.

ISO has a series of standards dedicated to clean rooms, outlining the practices and procedures required to manage the risk of contamination. The first two in the series have just been updated to take into account the latest technological developments and market requirements.

ISO 14644-1:2015, Clean rooms and associated controlled environments – Part 1: Classification of air cleanliness by particle concentration, and ISO 14644-2:2015, Clean rooms and associated controlled environments – Part 2: Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration, provide the framework for classifying and monitoring the cleanliness of the air in cleanrooms.

David Ensor, Chair of ISO/TC 209, the technical committee that developed the standards, which is led by ANSI, ISO member for the USA, under the administration of the Institute of Environmental Sciences and Technology (IEST), commented:

"Cleanrooms enable a large number of modern high-technology industries; therefore, the work of the technical committee will have widespread impact. The two revised ISO standards will improve the ability to quantify and manage airborne particle contamination worldwide.”

The ISO 14644 series is available from your national ISO member or from the ISO Store.
