This is the most frequently requested PDF. It defines the cleanroom classes from ISO Class 1 (the cleanest) to ISO Class 9 (the least clean). It also specifies the standard particle sizes (0.1 µm to 5 µm) and the calculation method for maximum particle concentration. If you only buy one PDF, start with Part 1.

Measuring how fast and consistently air moves through the room to ensure contaminants are efficiently removed.

Where air moves in a single direction at a uniform velocity.

The document is organized to help users select appropriate tests based on the cleanroom type.

Verifies that the pressure inside the cleanroom is higher than adjacent areas to prevent infiltration of contaminants.

Determines how quickly the cleanroom can return to its specified cleanliness level after a contamination event. Environmental Controls

Aris leaned closer. He was the lead contamination control officer at Nebula Dynamics. Their new “Class 3” cleanroom—the cleanest ever built, theoretically free of even a single 0.1-micron particle—was his masterpiece. And it was not compromised.
