The ASTM D1822 standard outlines test procedures to find the energy required to rupture tension-impact specimens of plastic or electrical insulating materials. Test materials that are too bendable or too thin to be tested in accordance with the ASTM D256 standard are ideal for this test along with more rigid materials. This standard is reported in SI units.

The test uses a pendulum impact testing machine with two pendulum falling arms. The two arms are connected by the testing specimen. ASTM D1822 specifies that the pendulum arms are dropped and the machine stops one arm at the lowest point and the kinetic energy of the second arm pull the connecting plastic specimen to failure. The energy that is required to cause the specimen to fail is the tensile impact energy.
