Manual Cupping Tester
The TQC Manual Cupping Tester is a revolutionary apparatus for testing the resistivity of coatings at various stages of deformation in accordance with ISO 1520.
Features
- 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.
- Low effort operation
- Small Footprint
- On request left hand model available
- Robust in design, this instrument is precision-machined
- Always clean the instrument using a soft dry cloth. after use. Never clean the instrument by any mechanical means such as a wire brush or abrasive paper.
- Annual calibration recommended
- Mandatory test in Qualicoat, QIB and GSB accredited laboratories.

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.
