Test results
The
Standard Spot Thickness
is the mean thickness (in nanometers) of the six thickest points in a 2.5 mm
2
area as defined in the ASTM D3241 / IP 323 test method.
The area shape of the Standard Spot can be rectangular, square or circular. Each shape type consists of six
(6) adjoining measured points among a total of 1200 points. The instrument automatically detects these
six adjoining points among all 1200 registered thickness values. This surface corresponds to a 2.5
mm
2
area. The average thickness value of these 6 points is reported as
Standard Spot Thickness
value.
The figure below provides an illustration of typical area shapes (or types) equivalent to 2.5 mm2 on the
heater tube surface.
The
Deposit volume,
expressed in mm
3
,
is the calculated total deposit volume deposited on the test
section of the heater tube surface.
The
3D deposit profile
s the X, Y and Z graph of the deposit on the surface of the heater tube. It is
expressed in nanometers. When the Standard Spot value is below 100nm, the thickness scale is fixed at
100nm and automatically becomes dynamic when the Standard Spot value exceeds 100nm.
The red color on the graph shows the area where the deposit thickness is greater than 85 nm.
It is possible to rotate and/or zoom the 3D graph.
To do so, touch the graph area and move your finger to obtain desired viewing angle. In order to zoom
the graph a mouse should be connected to the DR 10. Then use the mouse rotating knob to zoom the 3D
graph.
