ISO 14644-1, “Cleanrooms and associated controlled environments — Part 1: Classification of air cleanliness,” has been the go-to document for cleanrooms here in the U.S. ever since FED-STD-209 was cancelled back in 2001. Now ISO Committee TC 209 has issued the ISO/DIS 14644-1 draft for a proposed 2nd Edition. If you like to take a look at upcoming changes, or make comments, this is your chance! Voting on this draft document will happen on November 18th. But you’ll need a copy in order to review the updates and you can get yours from Document Center Inc. now.
ISO 14644-1 provides you with information on how air cleanliness is classified according to the concentration of particulate matter. It’s one of an 11 part series addressing the whole issue of cleanrooms and is the starting point for implementation of the series.
The new draft ISO/DIS-14644-1 covers classification of particle populations based on particle size that has a lower limit of 0.1 µm to 5 µm. It uses light scattering (discrete) airborne particle counters (LSAPC) to determine the concentration of these particles. This is done through the use of designated sampling locations.
Of course, until the draft is adopted and published, the current ISO 14644-1 1st Edition remains current. However, if both parties agree, the new draft document can be referenced in contracts.
If you’re in the aerospace, microelectronics, pharmaceuticals, medical devices, healthcare, or food industries you may find a need to provide a controlled environment during processing. This is where the ISO 14644 series comes in, since it is the core standards set for accomplishing contamination-sensitive activities.
