IEST publishes contamination control Recommended Practice on cleanroom design
The Institute of Environmental Sciences and Technology (IEST) has published a newly revised Recommended Practice (RP) that explores the factors to consider in the design of cleanroom facilities and provides a framework to establish performance criteria.
Aimed at cleanroom designers, constructors, owners and users, IEST-RP-CC012.2: Considerations in Cleanroom Design is organised into two primary sections: planning and design requirements. The planning section helps users develop a utility matrix to establish the equipment and processes to be used in the cleanroom, to determine the manufacturing layout, and to identify relevant contamination control, life safety, and environmental issues. Ergonomics, budget, and schedule projections are also reviewed.
The section on design requirements discusses each of the facility systems and covers the following topics:
• Cleanroom airflow system guidelines, with subsections on filtration, airborne molecular contamination control, and HVAC system configuration.
• Energy efficiency, including initial costs, life-cycle costs, and reducing consumption.
• Alteration of existing facilities, logistics involved in remodeling a cleanroom, and potential impact to operations.
• Factory automation and facility monitoring systems.
• Cleanroom construction protocol, including an in-depth section and a supplementary appendix that provides a detailed sample protocol document.
