What is involved in cleanroom certification?
February 2, 2012 by Renzo Cleanroom certification involves checking the cleanroom for specific parameters to ensure that it is built to the proper set of requirements. The room is also routinely retested to the same factors to ensure the quality has not changed during operations conducted in the cleanroom space.
When a cleanroom is certified to a specific class, it must operate according to standards that meet or exceed the ISO parameters of that class under a specific occupancy status.
