6 Operation
6.1 Summary of Test Method
A quantity of 65 grams of sample is heated in a
crucible at 250°C with a constant flow of air drawn
through it for 60 minutes. At the end of the test, the
sample is cooled and reweighed. The loss in mass
of the oil is then determined.
6.2 Analysis Setup Procedure
WARNING:DO NOT INSERT THE CRUCIBLE
INTO THE BATH UNTIL THE SOFTWARE
PROMPTS THE USER AT THE START OF
OPERATION.
1. Press the Start Analysis button on the main
menu screen (Figure 5) to open the analysis
startup panel. See Figure 8 below:
Figure 8: Analysis Startup Screen
2. Touch the Analysis Name field to identify the
sample. An on-screen keyboard will pop up
(See Figure 9 below). The analysis name
entered will automatically be listed as the test
title in the results browser. This will allow the
operator to easily recognize the analysis when
using the results browser for review.
Figure 9: On-Screen Keyboard Pop-Up
NOTE:If the analysis name is left blank the
analysis will not start.
3. Select the method by touching the Method
field. Method A is shown in Figure 8 above.
Method A: Temperature Control via PT100
probe in the Heating Block (Bath)
Method B: Temperature Control via PT100
probe in the Crucible.
4. Select the set-point temperature for the test
based on the selected method. Switching the
method will automatically change the
temperature to that prescribed by the method.
5. Weigh the empty crucible without the cover to
the nearest 0.01g and enter the measured
weight.
6. Pour 65g ± 0.1g of sample into the crucible and
enter the measured weight to the nearest 0.01g
into the dedicated fields.
7. When all of the above parameters are entered,
start the analysis by pressing the START
button.
WARNING:DO NOT INSERT THE CRUCIBLE
INTO THE BATH UNTIL THE SOFTWARE
PROMPTS THE USER AT THE START OF
OPERATION.
8. According to the method and temperature
selected, the bath will heat to the prescribed
set-point.
NOTE: The initial heating phase will show the
bath’s temperature even if method B was
selected. During this phase the graph will not
display data and the aspiration will remain idle.
9. While the bath is heating, ensure the glassware
is correctly set-up as shown on Page Figure 1,
Page 6. Verify that the manometer is level and
fill with water as needed so that the inclined
scale reads zero. Make sure the bleed valve
is fully open.
10. Once the bath has reached the set temperature
an audible alarm will sound and the Crucible
Prompt will appear on the screen. See Figure
10:

K441XX Automatic Non-Woods Metal Noack Evaporative Apparatus
Operation and Instruction Manual
K441XX-Manual - 11 -
Figure 10: Crucible / Bath Ready Prompt
11. The shut off chime button will appear at the
top right corner of the screen when the acoustic
alarm is sounded. The volume of the chime is
very loud so the operator may want to shut off
the chime for the current alarm.
NOTE:Shutting off the chime will only silence
the current crucible alarm. Therefore, future
alarms or prompts will still give off an audible
chime.
12. As per the on-screen instructions, ensure that
the crucible’s cover is correctly screwed on the
crucible’s body.
13. Insert the crucible into the bath and connect the
extraction tube to the Y shaped pipe on the
Woulff bottle as illustrated on Page 6, Figure 1.
NOTE:Ensure that the sample PT100
temperature probe is inserted into the crucible
and connected to the analyzer even if Method A
has been selected.
14. Once the crucible is inserted and the extraction
tube is connected, you may touch the screen to
start the vacuum and the analysis.
Figure 11: Aspiration Activation Screen
15. The aspiration / vacuum will now be activated.
See Figure 11 above. Regulate the aspiration /
vacuum to -2 mbar by slowly closing the bleed
valve halfway and regulating the vacuum
regulator on the analyzer’s side in order to
reach 20 ± 0.2mm on the inclined manometer (-
2mbar on screen).
16. The Aspiration label at the right side of the
screen will silently flash during this phase until
the aspiration reaches its desired setting and is
stabilized.
NOTE:Although the aspiration level should
automatically be maintained at -2 mbar it may
need to be readjusted at times due to the
heating vapor tensions. An acoustic alarm will
sound to alert the operator when the aspiration
level derives from the prescribed tolerance
range. It is imperative the aspiration is
readjusted in the shortest time possible.
17. Once the aspiration has been regulated, touch
the screen to start the analysis. The analyzer
will check if the aspiration is stable, if not, the
instructions for its regulation will pop up again
to allow the operator to repeat the procedure.
6.3 Test Procedure
1. The Method icon is disabled while the analysis
is running. If Method B was chosen, the graph
will show the Sample PT100 probe
temperature. The Start Analysis button will
become a STOP button, allowing the operator
to interrupt/abort the analysis.
2. If the analysis is interrupted within 5 minutes
from the start, any collected data is discarded
and the analysis will not be recorded,

K441XX Automatic Non-Woods Metal Noack Evaporative Apparatus
Operation and Instruction Manual
K441XX-Manual - 12 -
otherwise, even an incomplete analysis running
longer than 5 minutes will be recorded.
3. The status bar will describe the progress of the
analysis. In the bottom right hand side of the
screen the graph will display the temperature
data.
4. An alarm will sound along with a full screen
notice three minutes before the end of the
analysis. See Figure 12 below. Touch the
screen to shut off the alarm and close the full
screen notice. The status bar will display the
countdown to the end of the analysis.
Figure 12: End Analysis Screen
5. As the analysis is approaching the end, prepare
3 cm deep water bath at ambient temperature.
This will be used to cool down the crucible;
therefore it should be large enough to hold a
sufficient amount of water. Sufficient cool down
of the crucible will take approximately 30
minutes so accommodate a water bath where
the crucible can safely rest without interfering
with regular laboratory activities. (A laboratory
sink would be sufficient so long as no
interference occurs).
6. When the analysis time reaches 60 minutes
(the countdown reaches 0), a new alarm will
sound. Touch the screen to stop the alarm,
then CAREFULLY remove the crucible and
place it in the above mentioned water bath. Let
the crucible rest in the bath for 30 minutes.
NOTE: WHILE REMOVING THE CRUCIBLE
AND PLACING IT IN THE WATER BATH
MAKE SURE THE SAMPLE DOES NOT
SPLASH THE CRUCIBLE’S COVER.
7. After 30 minutes, carefully dry the outside of the
crucible then, unscrew the cover.
NOTE: This step should be performed without
tilting the crucible. THE SAMPLE SHOULD
NOT SPLASH THE CRUCIBLE’S COVER.
8. Reweigh the crucible with the remaining (un-
evaporated) part of the sample to the nearest
0.01g.
9. In the Results Browser enter the final weight.
The analyzer will calculate the final result.
6.4 Analysis of the Results
Subtract the empty crucible’s weight from the end
result in order to maintain the weight of the
remaining sample. The result of the following
formulas will provide the value of Noack
Evaporation Loss (Test Method D5800)
Method A:
(B-A) – (C-A)
Evaporation Loss = ――――――――
B-A
Where:
A= Empty Crucible weight
B= Crucible plus Sample weight
C= Crucible plus Sample after 1
hour of heating
Method B:
[(M1-M2)/M1] x100
Where:
M1= sample weight before the test
M
2= sample weight after the test
The final result is given to the nearest 0.1%
on both methods
NOTE:The analyzer is able to perform all
calculations on the above mentioned formulas, the
operator is only required to:
Note and introduce the empty
crucible’s weight
Note and introduce the sample’s
weight before the test
Note and introduce the crucible’s
plus sample’s weight after the test
The analyzer automatically gives the result
correlation between the two procedures as
prescribed in the ASTM D5800 method:
Result on B= 1.030 x Result on A
Result on A= 0.970 x Result on B
