Need help or have a question? Standards can be obtained from appropriate standards authorities. A number of test samples are then impacted to determine an appropriate starting point for the weight of the dart. Test method A specifies a dart with a 38 mm 1.
The mounting bracket is adjusted to the appropriate drop height, and the dart is inserted into the bracket. Film samples that can be cut to mm x mm 9″ x 9″ specimens A minimum of 30 specimens are required for the test Data: The dart is released to drop onto the center of ieo test specimen.
The method defines the dart size and the drop height for the dart. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Depending upon the expected impact strength of the test sample, either Method A or Method B is chosen.
This test uses a single dart configuration and a single drop height, while varying the weight of the dart. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Drop Dart ASTM D, ISO
The test specimen is clamped securely in a pneumatic ring at the base of the drop tower. The method to analyze this test data is called the “Bruceton Staircase” method. A series of 20 to 25 impacts are conducted. Falling dart impact is a traditional method for evaluating the 77655-2 strength or toughness of a plastic film.
