This testing device confirms to the standards of ISO3537and GB15763.3. It is applicable for the impact performance test of the equipment enclosure. It has the advantages of accurate performance and convenient operation as well as reasonable layout. Adjusted to a certain height, the steel ball, whose weight is required, falls down to hit the testing sample. Then the tester can judge the quality of the sample according to the damage degree of the testing sample. It can be used in the fastness test of the enclosure with the material of plastic, ceramic, acryl and Glass fiber.
