asmt The geometric uniqueness of the impactor head configurations prevents any comparison or correlation of testing results on samples tested with differing impactor head configurations. Any flat specimens can be tested – the preferred test sample is a mm 4″ disk or plaque.
Compound qualification, finished product quality control, environmental and weatherability research and development studies, and fabrication tolerance prediction constitute useful applications.
If a test sample fails, the drop height is d422 by one unit.

Historical Version s – view previous versions of standard. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. Then a series of 20 impacts are conducted.
The test is often used to specify appropriate materials for applications involving asgm or to evaluate the effect of secondary finishing operations or other environmental factors on plastic impact properties.
Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
