For optimum results using the staircase method, a minimum d4262 30 test samples are necessary. Any flat specimens can be tested – the preferred test sample is a mm 4″ disk or plaque.
Formally confirming that your products and services meet all trusted external and internal standards. If a test sample passes, the drop height is increased by one unit.

Validating the specifications, value and safety of your raw materials, products and assets. These notes and footnotes excluding, those in tables in figures shall not be considered as requirements of this standard. The test sample rests on a base plate over an opening of specified diameter. An “impactor” sits on top of the test sample with a nose of specified radius in contact with the center of the test sample.

Assurance Testing Inspection Certification. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
A weight is raised inside a guide tube to a predetermined height, then released to drop onto the top of the impactor, forcing the nose through the test sample. It is the responsibility of aastm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Compound qualification, finished product quality control, environmental and weatherability research and development studies, and fabrication tolerance prediction constitute useful applications.
Falling dart impact, also known as Gardner impact, is a traditional method for evaluating the impact strength or toughness of a plastic material.
If a test sample fails, the drop height is decreased by one unit. There is no known ISO equivalent to this standard. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Need help or have a question?
