ISO4406:1999 Alarm Levels
ISO4406:1999 represents cleanliness using codes for the number of particles greater than 4, 6 and 14µm. These
codes can be used as limits for the alarms by selecting the ISO4406:1999 test Format and then entering values as
required. As an extension to ISO4406:1999 it is also possible to specify codes for the other measured sizes too. If
this is not needed then the entries can be left blank.
NAS1638 Alarm Levels
Figure 6.25
NAS1638 can be used by selecting this as the test Format. The headings and boxes for the available settings
change appropriately. NAS1638 represents the overall cleanliness level as a single code, this being the highest of
the individual codes generated for each defined particle size. Hence we have the option of setting a limit on this
overall contamination class (the Basic Class), or we can set individual limits on any combination of the classes for
the defined particle size ranges.
