Cleanroom ISO Ratings - Get the Facts!

Cleanroom facilities are dedicated to specialized industrial manufacturing or scientific research, and are categorized by their ability to clean particulates in such specialized spaces. Based on the room’s ability to keep the air clean, the International Standards Organization assigns an ISO Cleanroom Rating. The room is cleaned by turning the air over via a high efficiency particulate air (HEPA) filtration system, which filters the air in per cubic meter as it flows through the system.

While luminaires themselves do not carry ISO ratings, they are designed with specific features that support the stringent airborne particulate requirements of ISO rated spaces. When specifying lighting for these spaces, their design must support the specific ISO rating of their intended application.
