Free falling dart impact tester



Free falling dart impact tester  BMC-AB  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 impact testing machine controlled by microcomputer, automatic calculation sample resistance to impact energy and impact curve, specimen clamping fixture, with double cylinder clamping, foot switch 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.

 Test principle

First select test method, then estimate the initial quality and △ m value to begin test.If the first sample damaged,reduce quality by weight △ m ; If the first sample not damaged ,increase weight by a weight △ m in order to test the quality. In short, the use of weight to reduce or increase the quality depending on the previous sample damaged or not. Calculate total N damaged sample after test 20 , if N is equal to 10, the test is completed; if N is less than 10, to continue the test until the supplementary sample N equals 10; if N is bigger than 10, continue until the not damaged sample total the equal to 10; Finally calculate impact results by the falling dart impact tester automatically .
