Understand the international ISO cleanliness standards (ISO 4, ISO 5, ISO 6, etc.) and how they correlate to the U.S. Fed-Std 209E designations (Class 10, Class 100, Class 1,000, etc.). This guide also discusses other key cleanroom recommendations on cleanroom air change and velocity rates, clean room ceiling fan coverage, positive vs. negative internal cleanroom air pressure, and laminar vs. turbulent air flow.
This tutorial provides practical tips for correlating the desired cleanliness level (per Fed Std 209 and ISO standards) to the required number of FFUs. Also provides guidelines for specifying lights based on the type of operations being conducted.
