What is a Cleanroom?

What is a Cleanroom?

ISO 14644 defines a cleanroom as;

“A defined space within which the number and concentration of airborne particles is controlled and classified, and which is constructed and operated in a manner to control the introduction, generation, and retention of contaminants inside the space.”

ISO 14644 is the global standard for cleanroom design and validation, but some industries and countries do still reference the old American Federal Standard 209D which defines a cleanroom as; 

“A room in which the concentration of airborne particles is controlled to specified limits.”
