ASTM D4226 – 16
The test is often used to specify appropriate materials for applications involving impact or to evaluate the effect of secondary finishing operations or other environmental factors on plastic impact properties. These notes and footnotes excluding, those in tables in figures shall not be considered as requirements of this standard. Assurance Testing Inspection Certification.
Certification Formally confirming that your products sstm services meet all trusted external and internal standards. If a test sample passes, the drop height is increased by one unit. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Validating the specifications, value and safety of your raw materials, products and assets. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Need help or have a question? An “impactor” sits on top of the test sample with a nose of specified radius in contact with the center of the test sample.
Gardner Impact ASTM D, D
The test sample rests on a base plate over an opening of specified diameter. The most common method to analyze this data is called the “Bruceton Staircase” method. Any flat specimens can be tested – the preferred test sample is a mm 4″ disk or plaque. The geometric uniqueness of the impactor head configurations prevents any comparison or correlation of testing results on samples tested with differing impactor head configurations.
Equivalent surface conditions are more likely to occur when specimens are prepared by compression molding or extrusion than by injection molding.
Falling dart impact, also known as Gardner impact, is a traditional method for evaluating the impact strength or toughness of a plastic material. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not d42226 standard.
Historical Version s – view previous versions of 4d226. 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. Compound qualification, finished product quality control, environmental and weatherability research and development studies, and fabrication tolerance prediction constitute useful applications. Formally confirming that your products and services meet all trusted external and internal standards.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. If a test awtm fails, the drop height is decreased by one unit. Link to Active This link will always route to the sstm Active version of the standard.
Standards can be obtained from appropriate standards authorities.
Auditing Consulting Sourcing Training. For optimum results using the staircase method, a minimum of 30 test samples are necessary. Then a series of 20 impacts are conducted. There is no known ISO equivalent to this standard.
