TQC BD3000 Conical Mandrel Bend Test
The Conical Mandrel Test BD3000 is a laboratory apparatus to bend coated test panels over a conical shaped mandrel in order to assess the resistance of a coating, paint or varnish, to cracking and/or detachment from a metal test panel under standard conditions.
Features
- Sturdy apparatus made of a combination of anodized aluminum and stainless steel.
- Ergonomic clamping device for test panels and large knob on bending arm for easy and smooth bending.
- Test apparatus used with wet and powder coatings in coatings in coating manufacturers laboratories and qc-labs of coating applicators.
- Special Care: Make sure all actions such as the clamping and bending are carried out without using any heavy forces, don't exceed the max panel thickness. Check the mandrel visually for mechanical damages or marks. Make sure to keep fingers and other body-parts clear from the bending area when performing a test.

- Data
-
Mandrel Range: 4 to 38 mm dia. Test Panel Size: 100 x 180 mm Max. Panel Thickness: 0.8 mm Apparatus Dimensions: 110 x 250 x 150 mm Weight: 4200 grams
Standards

Procedure
- Position the apparatus such that the fixation clamp (1) are facing forward.
- Loosen the fixation clamp and move the bending-handle (2) in the direction of the arrow so it is positioned at the side as the fixation clamp.
- Position the test panel with the coating facing forward (direction of operator) between the conical mandrel and the steel bending bar so that the panel can be secured in place with the clamping device (3) and tighten it with the clamp.
- Now slowly move the bending-handle (2) to the other side of the apparatus thus bending the test panel over the conical mandrel.
- Visually observe the test panel and check for cracks. If any have occurred note the diameter (3) of the beginning and end of the crack.
- Loosen fixation clamp (1) and remove test panel.
