TQC MANUAL CUPPING TEST

SP4400

1 SAFETY PRECAUTIONS

• Never put limbs in the clamping area.

• Always have the clamp properly tightened during testing

• Never test chattering or breaking materials like glass or acrylics that chatter when

exerted to high forces.

• Avoid using it in over-high or over-low temperature environment .

• Avoid humidity .

2 PRODUCT DESCRIPTION

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.

5 PREPARATIONS

• Place the instrument onto a firm strong bench, orientate the instrument with panel holder to the operator,

permitting sufficient room to operate the handle and observe the deformation of substrates.

• As standard the device is supplied for right-handed operating. Make sure there is enough room at the side

of the handle and this side is clear of sharp objects.

• Place the digital micrometer on the cupping tester as shown below.

Insert the micrometer in the
designated hole on top of the TQC
Manual Cupping Test.

6 PERFORM A MEASUREMENT

• 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 drive shaft and cause
deformations that could render the device unusable.

• Close the camp 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 to 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.

Ensure it is straight and pressed
against the housing.

Keep the micro meter secure and
straight and fix the micrometer by
using a 1mm Allen key.
