Clean room —a room in which the concentration of airborne particles is controlled to meet a specified airborne particulate cleanliness class. (c) the requirement and limit for this area will depend. A class 5 room can have an air change rate of 400 to 600 times per hour while a class 7 room can change at 50 to 60 changes per hour. More accurately, a clean room has a controlled level of contamination that is The air system should be provided with appropriate filters such as hepa for grades a, b and c. Grade a is the cleanest, for sterile operations, through to grade d for packing or support operations.

Up to class a, no purity classes may be skipped.

Grades a and b correspond with class 100, m 3.5, iso 5; Grade a is the cleanest, for sterile operations, through to grade d for packing or support operations. The air system should be provided with appropriate filters such as hepa for grades a, b and c. Clean rooms and controlled environments fda vs. (b) the guidance given for the maximum permitted number of particles in the “at rest” condition corresponds approximately to the us federal standard 209e and the iso classifications as follows: Controlled area is used for compounding, and manufacturing process where in final product is made sterile in later stage, by terminal or filtration sterilisation( class 1000, 10000).

The class of a cleanroom is found by measuring the number of particles ≥ 0.5 µm in one cubic foot of room air, and determining which class limit is not exceeded; Grade a is the cleanest, for sterile operations, through to grade d for packing or support operations. Clean room are classified as class 10 to 10000000, read below in detail. Clean rooms and controlled environments fda vs. Class d must pass through class c and b to operate in cleanroom class a.

This metric nomenclature is also accepted in the most recent 209e version of the standard. Given in the earlier 209 a to d versions, are shown in table 1. These grades can be related to the iso classes. A cleanroom must have less than 35, 200,000 particles >0.5 micron per cubic meter and 20 hepa filtered air changes per hour. Iso 8 is the least clean cleanroom classification.
