Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. The test sample rests on a base plate over an opening of specified diameter.
Assurance Testing Inspection Certification. Certification Formally confirming that your products and services meet all trusted external and internal standards. Then a series of 20 impacts are conducted. If a test sample passes, the drop height is increased by one unit. Equivalent surface conditions are more likely to occur when specimens are prepared by compression molding or extrusion than by injection molding.
Standards can be obtained from appropriate standards authorities. Auditing Consulting Sourcing Training.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. 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.
Specific precautionary statements are given in Section 8. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. Validating the specifications, value and safety of your raw materials, products and assets. 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 decreased by one unit. Assurance Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
Falling dart impact, also known as Gardner impact, is a traditional method for evaluating the impact strength or toughness of a plastic material. Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
An “impactor” sits on top of the test sample with a nose of specified radius in contact with the center of the test sample. The test is often used to specify appropriate materials for applications involving impact or e4226 evaluate the effect of secondary finishing operations or other environmental factors on plastic impact properties.
For optimum results using the staircase method, a minimum of 30 test samples are necessary. The geometric uniqueness of the impactor head configurations prevents any comparison or correlation of testing results on samples tested with differing impactor head configurations. Inspection Validating the specifications, s4226 and safety of your raw materials, products and assets. Formally confirming that your products and services meet all trusted external and internal standards.
