cleanroom classification

Cleanroom classification refers to the level of cleanliness in an environment, specifically how many tiny particles are allowed per cubic meter or foot of air. The higher the classification, the cleaner the space. These standards, set by organizations like ISO or Federal standards, help ensure that sensitive processes—such as electronics manufacturing or pharmaceuticals—aren't contaminated by dust or microbes. For example, an ISO Class 5 cleanroom permits fewer particles than an ISO Class 8, indicating a stricter environment. This classification guides the design, operation, and maintenance to keep the environment within targeted cleanliness levels.
