Property information for specific grades of resin are available in the Prospector Plastics Database. Property Search let's you search for plastics by more than 400 material properties. Tensile Impact - ASTM D1822The amount of energy per unit area required to break a specimen under tensile impact. This test is used for materials that are either too flexible or too thin to be tested with ASTM D256. Strain rate is somewhere between that of ASTM D256 and ASTM D638. 
Before Impact
After ImpactThe test specimen is carried by the pendulum of the tensile impact machine. The pendulum impacts a set of anvils so that the impact load is carried by the test specimen (see figures). Two test specimen types are used, Type S (Short) and Type L (Long). Type S specimens exhibit low extension and tend to produce brittle fractures. Type S specimen results are more reproducible, but offer less differentiation among materials. Type L specimens exhibit higher extension.
