FB-30J Falling Dart Impact Tester FB-30J Falling Dart Impact Tester is designed to determine the impact resistance of packaging materials, such as plastic films, laminates, and paper, by means of a free-falling dart from a specified height. This instrument is designed according to ASTM D1709 and ISO 7765-1, using methods A and B. • Fully automated testing process without manual calculations improves work efficiency. • Two test modes, A and B, are available. • Electromagnetic Dart Release Mechanism • The falling dart operates on the principle of electromagnetic suspension and can be released automatically. This instruments conforms to multiple international standards ASTM D1709, ISO 7765-1, JIS K7124-1 The manufacturer reserves the right to improve product performance and parameters

Test Principle At the beginning of the test, select the test method as the first step, estimate an initial mass and △m value, and then conduct the test. If the first sample is damaged, use the weight △m to reduce the falling mass; if the first sample is not damaged, use the weight △m to increase the falling mass for the next test. In short, the use of weights to reduce or increase the falling mass depends on whether the previous sample is damaged. After 20 samples are tested, calculate the total number of damaged samples. If n is equal to 10, the test is complete; if n is less than 10, continue...
