September 10–Revised Recommended Practice is now available. The experts of IEST Working Group-CC006 have finished their revision of IEST-RP-CC006.3, Testing Cleanrooms. This updated edition of the document provides methods to assist planners, designers, manufacturers, and customers in preparing detailed specifications for cleanroom procurement and for assuring cleanroom operational compliance.
This Recommended Practice (RP) describes a set of recognized, standardized test procedures for determining cleanroom and clean zone performance. The principal purpose of performance testing is characterization of airborne particulate cleanliness in accordance with ISO 14644-1 Cleanrooms and associated controlled environments-Part 1: Classification of air cleanliness. Additional tests, such as those related to airflow characteristics, sources of particles, room pressurization, and environmental issues, provide a more complete characterization.
