The DB3 is a fully manual device for impact resistance testing of filters, in compliance with ISO 18526-3:2020.
The test uses a steel ball with a diameter of 16 mm and a minimum mass of 16 g, dropped from a height of 1.27 meters.
The drop height is adjustable, allowing testers to simulate a variety of impact conditions.
A magnet holds the ball in place, and it is released using a lever mechanism.
A protective shield at the base contains any fragments in case of lens breakage, ensuring a safe and controlled test environment.
Drop ball test devices are used to assess the impact resistance of sunglass lenses and safety eyewear.
During the test, the lens or eyewear sample is placed on a stable, rigid support. A steel ball is then dropped from a specific height, freely and without additional force, directly onto the surface of the sample.
After the impact, the sample is inspected for any visible damage—like cracks, breakage, or permanent deformation.
The test is considered successful if no damage is found that could compromise the product’s safety or functionality.
