Understanding ISO 21501 4: On Demand Webinar

ISO 21501-4 has two main goals; to improve instrument-to-instrument (particle counter) data correlation and count accuracy, and to enhance compliance with ISO 14644.

By the end of this webinar, you should have a good understanding of the following concepts and how they affect your cleanroom particle counting efforts:

How to be compliant with the most recent particle counter calibration requirements
particle counter Sampling flow rate
particle counter Counting efficiency
Particle counter resolution
Pulse height analyser (PHA)
False count rate
Particle size setting
Coincidence loss at maximum particle concentration
Maximum particle number concentration
