Falling Dart Impact Tester GBD-L2 Introduction The GBD-L2 Falling Dart Impact Tester is suitable for testing materials such as plastic films or sheets less than 1 mm thick, as well as steel coatings. It measures the energy (expressed in mass) required to break plastic film and sheet specimens under the impact of a free-falling dart from a given height. This impact resistance test prevents surface damage to packaging caused by insufficient toughness due to impact or drops, effectively protecting products from damage during distribution. It is suitable for scientific research, teaching, industrial and mining enterprises, laboratories, research institutes, and quality supervision departments. Test principle Select the test method (Method A or Method B), estimate an initial mass and Δm value, and begin Add.: No. 3, Linjiang Road, Huangpu District, Guangzhou, Guangdong Province, China

the test. If the first specimen breaks, use a weight Δm to reduce the falling mass. If the first specimen does not break, use a weight Δm to increase the falling mass. Continue testing in this order. In short, whether to use a weight to reduce or increase the falling mass depends on whether the previous specimen broke. After testing 20 specimens, calculate the total number of breakages, N. If N is 10, the test is complete. If N is less than 10, add additional specimens and continue testing until N equals 10. If N is greater than 10, add additional specimens and continue testing until the total...

• The main unit is equipped with a color touch screen for convenient test operation. • The innovative mechanical design and user-friendly interface make the instrument easy to operate.

Method A, Method B, and single-piece test modes are available, making this instrument versatile. Electromagnetic clamping and automatic release effectively prevent system errors caused by human error. The intelligent testing process significantly improves work efficiency. Specimens are pneumatically clamped and released, reducing errors and test time. No manual drawing or marking is required during the test, as data parameters are displayed on an LCD screen. The test data is automatically recognized and calculated, eliminating the need for manual intervention. A built-in printer prints test reports....
