Understanding ISO 21501-4: Particle Counter Calibration
On Demand Webinar
ISO 21501-4 has two main goals; to improve instrument-to-instrument 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 calibration requirements
- Sampling flow rate
- 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
