The TQC-Sheen Cylindrical Mandrel Bend Test is used to evaluate the elasticity, adhesion, and elongation of paint applied to a metal panel in accordance with the TS EN ISO 1519 standard. For this test, a metal panel (maximum size: 150 x 100 mm) is bent over a cylindrical mandrel. As the mandrel diameter decreases, the stress on the coating increases. After bending, the test panel is inspected for cracks and damage.

A convenient desktop storage rack for 14 mandrels is optionally available and can also be wall-mounted.

Cylindrical bend testing is a mandatory procedure for laboratories accredited by Qualicoat, QIB, and GSB.

The TQC-Sheen Cylindrical Bend Test is also designed to comply with the latest revisions of ASTM D522, to test for cracking and detachment from the substrate when a coating, paint, varnish, or similar product is bent under standard conditions over a cylindrical mandrel.

This version of the cylindrical mandrel test device includes 7 mandrels according to the imperial measurement system:
1/8″, 1/4″, 3/8″, 1/2″, 5/8″, 3/4″, 1″.

  • Robust device made from a combination of anodized aluminum and stainless steel

  • Ergonomic clamping device for test panels

  • Well-designed lever for easy and smooth bending

  • Large test panel size: max. 150x100mm

  • Robust mandrel holder for desktop use or wall mounting.
