Correlation
The table shows the correla-
tion between Particle Sizes
Obtained using ACFTD (ISO
4402:1991) and NIST (ISO
11171) Calibration Methods
This table is only a guideline.
The exact relationship between
ACFTD sizes and the NIST sizes
may vary from instrument to in-
strument depending on the char-
acteristics of the particle counter
and original ACFTD calibration.
