Trend
The Trend functionality provides some information about the measurement
history
. It gives
the user the possibility to supervise the
chamber condition
. A chamber should have
normalization value as close as possible to the target values of a carbon black type. Like this
the normalization correction will be small.
No official indications (ASTM or other) are available for
Normalization but according to our observations, up to 4
DBP units (ml/100g) can at least be corrected. The trend-
graph shall help to observe how the values develop with
the wear of the chamber and shall enable to decide long
enough in advance when a replacement shall become
necessary. Note that a new chamber must be Pre-polish
before reliable data can be expected.
To view the trend list of the Normalization measurements
the group of carbon black has to be entered first. This is
done from the Figure 12 showing up the Trend function is
chosen.
We will show an example of Normalization measurements
on the following window. The
list
shows the dates of the
different normalization measurements and their results. In this example the results of the
class
“Hard”, method “OAN” are listed. The Status column shows if the measure was
“Accepted” or “Rejected”.
