IEST G-CC1001 – Counting Airborne Particles for Classification and Monitoring of Cleanrooms and Clean Zones

Technical Guide 1001 launches the series of Guides, with general coverage of methods for sampling air in clean environments using a discrete-particle counter (DPC) to determine concentrations of airborne particles.The protocols presented are applicable for any cleanroom occupancy state and apply to classification (in accordance with ISO 14644-1), as well as monitoring (in accordance with ISO 14644-2). Several terms specific to counting procedures are defined. This document also provides detailed setup procedures to complement the concise provisions of section B.4.3 of ISO 14644-1.
