CLEANROOM STANDARD

ISO 14644-1

FED STD 209E

definition

ISO 14644-1

cleanroom

A room in which the contamination of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation, and retention of particles inside the room and in which other relevant parameters. e.g. temperature, humidity, and pressure, are controlled as necessary

definition

FED STD 209E

cleanroom A room in which the concentration of airborne

particles is controlled and which contains one

or more clean zones

clean zone A defined space in which the concentration of

airborne particles is controlled to meet a

specified airborne particulate cleanliness class
