It is suitable for the determination of the impact resistance of plastic films, sheets and other materials in the packaging industry, film manufacturers, packaging material testing institutions, etc.

At the beginning of the test, first select the test method, estimate an initial mass and the value of △m, and then conduct the test. If the first sample is damaged, use the weights to reduce the falling body mass by △m; if the first sample is not damaged, use the weights to increase the falling body mass by △m and carry out the test successively. In short, the weights are used to reduce or increase the falling body mass, which depends on whether the previous sample is damaged. After testing 20 samples, calculate the total number of damaged samples N. If N is equal to 10, the test is completed; if N is less than 10, supplement the samples and continue the test until N is equal to 10; if N is greater than 10, supplement the samples and continue the test until the total number of undamaged samples is equal to 10. Finally, the system automatically calculates the impact result.

1.The instrument has two test modes, A and B.

2.Accurate test results, easy to operate, and automatically prints result data.

3.Menu-driven interface with color touch screen operation for quick and convenient setting of test parameters.

4.Simple instrument maintenance.

5.The falling dart uses the principle of electromagnetic adsorption and can be automatically released, effectively avoiding systematic errors caused by human factors.
