TQC Manual Cupping Tester
Article No. 12699
Manual Cupping Tester
Revolutionary apparatus for testing the resistivity of coatings at various stages of deformation in accordance with ISO 1520. The built in gear-box minimizes the manual force which is required to deform the test panel, allowing to perform a smooth deformation. The degree or deformation is digitally displayed at a resolution of 0.01 mm. Mandatory test in Qualicoat, QIB and GSB accredited laboratories.

More Information
Foil Clamp - For use with thin substrates (foils) like metal sheet brass and copper, an optional foil clamp (PA-920211) can be ordered. Thin substrates tend to curl on the sides and then cannot be removed properly from the clamping mechanism of the cuping test.
Sliding the foil clamp on top of the sample after the sample has been locked into the cupping test standard clamping mechanism will prevent the sample material to curl. After test the coil clamp is removed and the standard clamp is relesed where after the sample can be removed properly.
Standards
In accordance with ISO 1520
Procedure
- Place the test sample with the coated side up inside the clamp. Do not exceed the panel thickness as stated in the specifications and on the machine. Testing on thicker panels can damage the device shaft and cause deformations that could render the device unusable.
- Close the clamp to hold the panel in place. Do not use force when clamping, otherwise when removing the panel the required force to release the panel can be too high for the operator.
- Turn on the micrometer.
- Gently turn the handle to raise the indenter. To get an indentation speed of about 0.2mm/s requires about half a revolution per second.
- The test is carried out either to a predetermined indentation depth at where the panel is evaluated or defects in the coating or to the depth where the first defects in the coating form.
- After the results have been determined turn the indenter back to below the zero position.
- Release the sample clamp and remove the sample.
