Our new TQC Knock-out testpanels are designed to minimize the build-up of paint on the panel edges because of de knock-out frames. Also because of the 4 mm holes in the knock-out frames it is easy to hang the panels horizontally or vertically without leaving any marks.

All our knock-out panels are provided with a protective PE film on the prepared side (prepared side recognizable by its round edge in the right upper corner) which serves as protection against scratches, corrosion and finger prints. The film is easy removable after the panels are hanged.

The TQC knock-out panels meet the requirements for Qualicoat, GSB, QIB and ISO standards.

The panels are standard delivered in 2, 4 or 8 pcs per frame and packed in a resealable carton box.

Other shapes and sizes on request.

The TQC Bend Test Conical Mandrel "Pro" is a laboratory apparatus to bend coated test panels over a conical shaped mandrel in order to assess the elasticity or resistance of a coating-, paint or varnish to cracking, elongation and/or detachment from a metal test panel in accordance with ISO 6860 and ASTM D522. The conical shape of the bending area allows the deformation of the test panel and examination of the elasticity range of a coating over any diameter between 3.1 and 38 mm in one single test. The sample panel is secured to the apparatus by means of a quick lever handle that lock and unlocks the panel in a split second using just hand.


The TQC Impact Test is used to determine the impact resistivity and flexibility of coatings. The dual scale instrument is equipped with a special guidance which assures that the distance between each impact is always according to the standard. For correct positioning a spirit-level is built-in. Each Impact test comes as a complete set (instrument and accessoires) to perform a test according DIN/ISO 6272, ASTM D2794 and ASTM G14 Mandatory test in Qualicoat, QIB and GSB accredited laboratories. Standards for impact testing Below mentioned standards are a list of the possible standards.
