This Standard establishes the principles and basic methodology of a formal system
of biocontamination control (Formal System) for assessing and controlling biocontamina-
tion when cleanroom technology is applied for that purpose. This Standard specifies
the methods required for monitoring risk zones in a consistent way and for applying
control measures appropriate to the degree of risk involved. In zones where risk is
low, it can be used as a source of information.
