Other Standards
Although ISO 4406 is used extensively in the hydraulics
industry, other standards are occasionally required. Direct
comparison is not always possible, but this table
provides some estimates.

TheTarget-Pro 2 is calibrated with ISO MediumTest Dust (to ISO 11171).
The correlation between particle sizes and the ACFTD (old standard) to
the ISOMTD (new standard) is as follows :
ACFTD <1 5 15 25 30 50* 75* 100*
ISOMTD 4 6 14 21 25 38 50 68
* To be confirmed by NIST.
This table is only a guideline. The exact relationship between ACFTD sizes and the NIST
sizes may vary from instrument to instrument, depending on the characteristics of the parti-
cle counter and original ACFTD calibration.
