Description
AUTOMATIC CUPPING TESTER
TQC Sheen Automatic Cupping Tester 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.
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.
Mandatory test in Qualicoat and QIB accredited laboratories.
