24、gn IEST-RP-CC012.3 1 SCOPE AND LIMITATIONS 1.1 Scope This Recommended Practice (RP) makes recommendations regarding factors to consider in the design of cleanroom facilities. This discussion is limited to those environmental conditions that typically confront cleanroom designers and users. 1.2 Limit
25、ations This RP is limited to the design of cleanroom facilities. Equipment design is not within the scope of this RP, nor does this RP address process or operational considerations, except as these considerations relate to cleanroom design. This RP is intended to provide users with a means to establ
26、ish performance criteria for cleanrooms. The factors considered are those commonly encountered in cleanrooms, but discussion of these factors is not intended to be all-inclusive. The specified ranges and recommended criteria are intended only to provide a framework. Specific process or other needs m
27、ay dictate requirements beyond the scope of this document. This RP is not intended to supersede specific requirements established by a recognized national or international regulating body. 2 REFERENCES The following publications were used in the preparation of this document or are considered critica
