IEST updates and improves its Recommended Practice for testing ULPA filters

摘要

The Institute of Environmental Sciences and Technologies (IEST) has long been a leader in the area of cleanroom filter definitions and performance testing. IEST maintains recommended practices (RP) for the following filter-related topics: IEST-RP-CC001.3: HEPA and ULPA Filters IEST-RP-CC002.2: Unidirectional Flow Clean-Air Devices IEST-RP-CC006.3: Testing Cleanrooms IEST-RP-CC007.1: Testing ULPA Filters IEST-RD-CC011.2: A Glossary of Terms and Definitions Relating to Contamination Control IEST-RP-CC021.1: Testing HEPA and ULPA Filter Media IEST-RP-CC034.1: HEPA and ULPA Filter Leak Tests In addition, IEST Working Groups (WG) are developing recommended practices for areas such as "Design Considerations for Airborne Molecular Contamination Filtration Systems in Cleanrooms" and "Testing Fan Filter Units." Several of the abovementioned recommended practices have recently been revised and republished so that advances in air filter construction and testing can be included. As part of that overall upgrade to IEST's documents, WG-CC007 is putting the finishing touches on a revision of their recommended practice to be released as IEST-RP-CC007.2. The latest draft of this effort contains new information on a wide range of topics; however, the core content of the RP remains unchanged.
