Class 10000 Clean Rooms

Class 10000 Clean Rooms

Class 10000 clean rooms are the lowest level in Federal Standard 209 classification and never exceed 10000 particles per cubic foot. The airborne cleanliness classes in clean rooms and zones name their classes after the maximum number of particles allowed in the rooms at one time. Class 10000's ISO equivalent is ISO 7. Clean rooms are used where air is continuously filtered so tiny particles in the air don't damage highly sensitive technologies, and in class 10000, the air changes 40-60 times an hour. This class is the least strict when it comes to limitations and rules regarding cleaning, moving around and clothing, but there are still special procedures for each of these activities which must be followed in order to prevent contamination.

In class 10000 clean rooms, bunny suits do not need to be worn. Instead, shoe covers, lab coats, hair nets, safety glasses and gloves are adorned by everyone entering the room. The panel or wall material in class 10000 clean rooms is often made of white acrylic, steel or stainless steel, aluminum or polycarbonate. This class of clean rooms can be any of the 3 types-ball room, which are large and open rooms that are parts of the actual building, modular, which is a temporary and small room within a room, and soft wall, where the walls are made of tightly stretched or free-hanging fabric or plastic flaps. They may range in size from huge open spaces to tiny chambers. Temperature control and electrostatic discharge control are also possible in this class of clean rooms.
