Testing in Accordance with ASTM D3359:
1. Use the table below to select the appropriate cutting tool based on
the thickness of the coating to be tested.
Coating Thickness
µm
mils
0 - 50
0 - 2
50 - 125
2 - 5
2. Inspect the tool to ensure that the cutting edge of the blade is not
damaged or dulled. If the blade is not in suitable condition, follow
the steps in Preparing the PosiTest CH (pg. 2).
3. With the test panel on a rigid, flat surface, place the PosiTest CH
on the coated surface with the blade perpendicular to the coating,
and pull the tool across the surface to create a mark or scratch
approximately 20 mm (¾ in) long. After cutting, lightly brush the
surface with the included brush to remove any detached flakes of
coating.
4. Repeat step 3, producing another set of cuts at a 90° angle to the
first set of cuts, creating a lattice pattern on the surface.
NOTE:
All cuts shall mark or scratch the substrate or the test is con-
sidered invalid and should be repeated on a fresh test panel.
