A controlled surroundings for instance a clear zone or clean home is described by certification according to a suitable thoroughly clean room operational common. Parameters which have been evaluated include filter integrity, air velocity, air designs, air improvements, and force differentials. These parameters can impact the microbiological bioburden of the clear room Procedure. The look, development, and operation of thoroughly clean rooms differs greatly, making it tricky to generalize requirements for these parameters. An example of a method for conducting a particulate challenge test on the procedure by raising the ambient particle concentration in the vicinity of important function places and gear is produced by Ljungquist and Reinmuller.
