Steel Ball Impact Tester Function: Determination of whether the safety glazing material has a certain minimum strength and cohesion under impact from a small hard object Suitable for impact test of safety glass and tempered glass. Related Standard: ISO 3537 Road vehicles Safety glazing materials Mechanical tests Clause 6: 227 g ball test, Clause 7:2260 g ball test GB 15763.3 Safety glazing materials in building Part 3:Laminated glass Appendix B Drop ball impact specimen support Apparatus: 1) 1m/3m/5m Ball Drop Impact Testing Device 2) Adsorption and release device of steel ball 3) Steel ball 4) Supporting fixture size: 350 mm*350 mm or 660 mm*660 mm Technical Data: Hardened steel ball: 2260g ± 20g, diameter of approximately 82mm 1040g ± 10g, diameter of approximately 63 mm 227g ± 2g, diameter of approximately 38 mm Steel ball adsorption mode: Electrocircuit controlled electromagnet suction cup Lifting and lowering mode of control lever: manual or automatic Drop height of steel ball: 1m /3m/5m/12m, customizable Supporting fixture: Support size: 350 mm*350 mm and 660 mm*660 mm (Customized) Frame width: 15 mm Steel box height: 150 mm Rubber gasket: thickness 3 mm, width 15 mm, hardness shore A50 Interposed sheet of rubber: thickness 3 mm, hardness shore A50 Applied Test Pieces Size: 300 mm*300 mm and 610 mm* 610 mm 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.
