Abstract

The cleanlines of air required for clean rooms is defined in terms of nature, quantity, size distribution, test methods and removal mechanisms of contaminants. Test instrumentation is described and some practical limitations are given. Included is information regarding some of the changes recommended by the Institute of Environmental Sciences for the latest revision of Federal Standard 209. Some projections are made for what future clean room air cleanliness may be required. Present knowledge indicates that future cleanliness needs beyond the present limits may be restricted to very small, confined zones, where exposure to contamination is transient and of short duration.
