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. 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.
• Low effort operation
• Small Footprint
• On request left hand model available
Testing 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.
The sample test is placed coated side up inside clamp, not exceeding the panel thickness specification and the clamp is closed to hold panel in place without using force otherwise when removing the panel the required force to release the panel can be too high for the operator. Then the micrometer is turned on and the handle is gently turned to raise the indenter. To get an indentation speed of about 0.2mm/s requires about half a revolution per second.
