3. Testing
Procedure
Impact Test
The impact test can be performed
on the coated or on the uncoated
side of the test panel. Thus, the
indentation can be either an
intrusion or an extrusion.
• For testing place the panel on
the die with the coated side
either up or down depending
upon the application. Fix the
panel using the clamping
device.
• Raise the falling weight to the
required drop height and
release it.
• After every test check the
test panel for damage.
Testing should normally be started
at a low load (small weight, small
drop height). The impact energy is
higher by increasing the drop
height or by using an additional
weight until damage can be seen.
The test should be carried out in
at least 4 different places on the
test panel not less than 4 cm from
each other.
Limitation of Indentation Depth
Depending upon the test panel
thickness, distance rings (Cat.No.
PF-5533) can be fitted to limit the
indentation depth from 2 to 10
mm.
