ISO 4-5 (Critical)

ISO 14644-1 is the international standard for airborne particulate contamination levels in cleanrooms. In the operation of cleanrooms, many factors in addition to airborne particulate cleanliness must be considered in the design, specifications, operations and control of the controlled environment.

ISO 4-5 (Class 10-100 in former FED STD 209E) represents a critical environment and as such great care must be taken to ensure that all cleaning supplies that are introduced into this environment do not significantly contribute to the expected particulate burden.
