Cylindrical Mandrel Bend Test

SP1820 Complies to ISO 1519. Look up the appropriate standard for a correct execution of the test. Also refer to ISO 1512-ISO 1514-ISO 2808-ISO 3270. SP1822 Complies to ASTM D522

Cylindrical Mandrel Bend Test

The TQC Cylindrical Bend Test is used to determine the elasticity adhesion and elongation of paint on sheet metal in accordance with ISO 1519. A test panel (max. size 150 x 100 mm) is bent over a cylindrical mandrel. The smaller the diameter of the mandrel, the larger the tension on the coating. The test panel is then checked for cracks or damage in the coating.


The Cylindrical Bend Test is designed to perform tests according to the latest ISO standards. ISO 1519: "Assessing the resistance of a coating, paint, varnish or related products to cracking and/or detachment from a surface when, subjected to bending around a cylindrical mandrel under standard conditions".
  • Sturdy apparatus made of a combination of anodized aluminium and stainless steel.
  • Ergonomic clamping device for test panels and large knob on bending arm easy and smooth bending.
  • Large test panel size: max. 150 x 100 mm
  • Luxurious wall mounted / desktop mandrel holder
  • Though robust in design, this instrument is precision-machined. Always clean the instrument after use with a soft dry cloth. Do not use compressed air to clean the instrument.
