This device is designed to test the impact resistance of single-layer fusion-bonded epoxy (FBE) coatings in accordance with ISO 21809-2. In this method, a one-kilogram weight with a hardened tip of 15.8 mm in diameter is dropped on the sample from a height of one meter through a scaled weight guide.
The effect of the indenter tip on the impact resistance of the coating is checked with the help of the holiday test. It is worth noting that the device has a hardened base according to the standard.
Drop weight / impact test
These devices are designed and manufactured in order to check and test impact resistance (quick deformation by impact) in organic coatings and single and three-layer fusion-bonded epoxy (FBE) coatings in accordance with ISO 21809-2, ISO 21809-1 and ASTM D2794 standards. In this method, a weight specified in the standard (one kilogram) is dropped from a specified height of one meter, or a variable height (according to the standard), onto the coated sample, and the effect of the impact on the impact resistance of the coating is checked with the help of the holiday test and visual inspection.
Technical specifications:
- The device is designed and manufactured in accordance with ISO 21809-2 (2014) and ISO 21809-1 standards.
