Think your cleanroom surfaces are spotless?
ISO 14644-9 says — prove it.
In environments such as the semiconductor industry, EV battery manufacturing and aerospace assembly, even microscopic particles can compromise performance, yield, and reliability. That’s why ISO 14644-9 defines surface cleanliness by particle concentration — not appearance.
From verifying cleanliness of aerospace components, such as engine parts to checking the cleanliness of aircraft surfaces ensuring performance and safety. Learn how the Partsens prevents defects and improve product yield by verifying cleanliness.
It’s not about what looks clean.
It’s about what measures clean.
This standard provides validated methods to assess particulate contamination on solid surfaces and precision assembly fixtures. Engineers gain quantifiable criteria instead of subjective visual judgments.
