The TQC Automatic Cupping Tester allows to perform a cupping (Erichsen / Dent) test on coated steel panels to define the resistance of paint, varnish or related products to cracking and/or detachment from a metal substrate when subjected to gradual deformation by indentation under standard conditions.

The test is either used as a “pass / fail” test by testing to a specified depth or defining the minimum depth at which a coating fails by gradually increasing the indentation.

Constant deformation

The ISO1520 standard requires panels to be slowly deformed at a steady rate between 0,1 mm/s and 0,3 mm/s without interruption. Especially with thicker steel panels hand-operated testers not always allow an uninterrupted deformation. The Automatic cupping tester is driven by a micro-step controlled electro motor which allows precise and steady deformation with 0,01 mm steps. Uniquely this deformation can be paused / resumed.

Unique Interface

Each Automatic cupping tester is equipped with the Triple I ® Navigation Tool. This Intelligent Illumination Interface guides the operator through the TQC Sheen lab-machines. At each step of the operating menu the interface detects which buttons are active and indicates these by means of an illuminated red center This results in a very intuitive operating system which is enhanced with information on the machine’s full colour display.

Numerous set-ups

The Automatic cupping tester has numerous set-ups. The custom set-up optionally is password-protected, and after each set number of test runs statistics are shown. Also the illumination of the test specimen can be set-up. To guarantee maximum visibility of all possible types of surface including high gloss, matte or colored samples the TQC Sheen Automatic cupping tester is equipped with a complementary light system of which the colors can be changed to achieve maximum contrast. The strength of the LED’s is adjustable as is the direction of the light source.

The TQC Sheen Automatic cupping tester has a TQC Sheen-Bus connection (LinQ system not included).


The cupping test is mandatory in Qualicoat and QIB accredited laboratories.
