LTMC-A Falling Dart Impact Tester

LTMC-A Falling Dart Impact Tester

Free falling dart impact tester LTMC-A is used for determine the impact mass and energy when plastic film or sheet sample broken at a given height by free-falling ball. Free falling dart i mpact testing machine controlled by microcomputer, automatic calculation sample resistance to i mpact energy and impact curve, specimen clamping fixture, with double cylinder clamping, foot s witch operation, make the whole experiment process simple, convenient . Free falling dart impact tester is widely used in the quality inspection agencies, packaging production enterprises etc.

Principle

Before starting the test, choose test method, and estimate an initial mass and Δm. Start the test. If the first specimen fails, decrease the mass of the falling dart by Δm. If the first specimen is not a failure, increase the mass of the falling dart by Δm. Continue the test according to this rule. In brief, increase or decrease by Δm according to whether the former specimen is a failure or not. After 20 specimens, calculate the total number of failed specimens N. If N equals to 10, the test is over. If N is less than 10, add specimens and continue to test until N equals to 10. If N is greater than 10, add specimen and continue the test until the number of non-failure specimens reaches 10. Then the tester calculates the test results automatically according to specific formulas.
