Cleanroom classification can be confusing, especially when there are multiple standards used in multiple industries and there is overlap in those standards. Here we’ll focus specifically on ISO classes: what they are and why they matter.
What are the ISO classes?
The ISO classification system has eight classes, ISO Class 8 being the least controlled and ISO Class 1 being the most controlled.
Maximum Number of Particles in Air by Particle Size
|ISO Class||≥ 0.1μm||≥ 0.2μm||≥ 0.3μm||≥ 0.5μm||≥ 1μm||≥ 5μm|
Why does ISO classification matter?
Most laboratory and cleanroom applications require a controlled environment. The level of control depends on both the industry and the specific application. Cleanroom classes serve as a standard that can be easily referenced for the required level of environmental control. Additionally, they serve as a standard for certification to ensure that a cleanroom meets the proper level of control for the industry and the specific tasks performed in that cleanroom.
