Drop Ball Impact Test

The ball impact test is used to determine the indentation resistance and the flexibility of coatings with rapid deformation. By determining the resistance to deformation, conclusions can be drawn about the elasticity and adhesive strength and thus about the quality of a coating.
The device is equipped with a special guide, which guarantees that the distance between two stroke depths complies with the standard. A dragon-fly ensures the correct positioning of the device.
A test sheet is placed under a punch and then the drop weight is dropped from a predetermined height onto the positioned punch. The tested substrate or coating is assessed according to the degree of deformation and destruction.

Application Examples:

  • Assess the resistance of a coating to cracking and detachment from the substrate
  • Impact resistance of substrates
     

Test Standard:

DIN EN ISO 6272 1
 

Device Configuration:

  • Punch:
    • 12.7 mm
    • 15.9 mm
  • Drop height: according to individual requirements (up to approx. 105 cm)
  • Full scale values ​​(depending on the unit):
    • 100 cm
    • 10 N·m
    • 90 bf·in
Ball impact tester: A detailed view of the release mechanism is shown. The picture shows a vertical, long, slotted tube. Inside the tube is a drop weight with a mandrel pointing forward through the slot. This mandrel is mounted in a holding device. By turning the holding device, the mandrel is mechanically released and the weight can fall down.

Ball impact tester: A detailed view of the impact table is shown. The picture shows the impact table where the sample to be tested is placed. The sample is located in the slotted tube and is hit by the falling weight and pressed against the sample. A spirit level is built into the impact table so that the tester can be aligned.
