DB2
The DB2 is a semi-automatic device for impact resistance testing of filters, compliant with ISO 18526-3:2020.
The test involves dropping a steel ball with a diameter of 16 mm and a minimum mass of 16 g from a height of 1.27 meters.
The ball is released via a pneumatic button, guaranteeing a consistent drop every time the test is run.
The DB2 is equipped with a ball reservoir that can hold up to 30 steel balls (Ø16 mm), and a vertical drop tube precisely guides the fall.
At the base, a protective shield is in place to contain any fragments in the event of lens breakage, to safely contain debris and protect the operator.
Drop ball test devices
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.
