Drop Dart ASTM D1709, ISO 7765
Test method A specifies a dart 776-52 a 38 mm 1. The mounting bracket is adjusted to the appropriate drop height, and the dart is inserted into the bracket. A number of test samples are then impacted to determine an appropriate starting point for the weight of the dart.
The dart is released to drop onto the center of the test specimen. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
The method to analyze this test data is called the “Bruceton Staircase” method.
