Understanding ISO 21501-4 (128.5 KB)

Included with ISO 21501, there are four parts, of which Part 4 (Light scattering airborne particle counter for clean spaces) will be discussed here.

The documentation and approval of ISO 21501-2, -3, and -4 subsequently replaces and cancels ISO 13323-1:2000. The ISO 21501 standard widens the scope of analysis to include methodology for airborne particle counting and liquid particle counting (both light scattering and extinction methods). Specifically, ISO 21501-4 provides a calibration procedure and verification method for airborne particle counters to ...
