Plastic Shopping Bag Dart Impact TesterIt is suitable for determining the impact quality and energy of 50% of plastic film or sheet specimens when they are damaged under the impact of a free dart at a given height.
Plastic Shopping Bag Dart Impact TesterIt can also be called film dart impact tester, dart impact testing machine, film dart impact testing machine, dart impact tester, packaging impact tester, dart impact tester, dart impact performance tester, plastic packaging impact tester, film impact tester.
According to GB T 96391-2008 "Test Methods for Impact Resistance of Plastic Films and Sheets Free Dart Method Part 1: Step Method" The step method is divided into Dart Impact A Method and B Method.
The difference between the two: the diameter of the dart head, the material and the drop height are different. Generally speaking, method A is suitable for materials with an impact damage mass of 50g and 2000g. Method B is suitable for materials with an impact damage mass of 300g and 2000g. The step method of GB T 9639 and ISO 7765 is the equivalent method.
Method a: The diameter of the dart head is 38 1mm, and the dart head material is made of smooth, polished aluminum, phenolic plastic or other low-density materials with similar hardness, and the drop height is 066±0.01m。
B method: the diameter of the dart head is 50 1mm, the material of the dart head is made of smooth, polished stainless steel or other materials of similar hardness, and the falling height is 150 ±0.01m。In ASTM D1709, the diameter of the dart head for method A and method B is 38., respectively1±0.13mm and 508±0.13mm。
Plastic shopping bag dart impact tester test process
1) Turn on the instrument switch and select method A or method B as needed, and method A was selected in this test.
2) Adjust the drop height of the dart to 066 ± 0.01 m, adjust the adjustable bracket of the device so that the dart can hit the center of the specimen after it has been dropped.
3) More than 20 pieces of specimen with a size of at least 18 cm and 18 cm should be randomly cut from the surface of the sample.
4) Take one of the samples and put them on the lower grip to ensure that the surface of the sample is flat, press the foot switch, and the device will automatically clamp the sample.
5) Obtain the approximate impact damage quality of the sample through the ** test, and then insert the dart of this mass vertically into the magnetic connector, click the test option, and the dart will automatically fall and impact the sample.
6) Enter the damage of the sample into the equipment, and use the weight to increase or decrease the quality of the dart according to the damage of the sample.
7) Repeat (4) 6) until the number of broken or undamaged samples reaches the requirements, and the equipment automatically calculates and displays the impact damage quality.
