Pendulum Impact Testers
Notch toughness test
Test notch toughness of plastic and metal materials. Test standard rod-shaped, fitted notch, saved two aids is stressed in the middle of the length of a single hammer stroke and the pendulum is suspended on a command from above (Charpy hammer). The size of this nature is expressed by the maximum energy scale, which will draw the hammer. Commonly used in the range 0-450 J at an impact speed of 4-7 ms-1. Impact strength is given by the energy consumed in a broken test bars and the area (the smallest) cross rod. Is expressed in J.cm-2.
The work required to test a broken rod bearing notch impact test at the bend. Impact strength is determined in particular notch Charpy impact test or Izodovou test. In the Charpy test (common in Europe), the energy consumed covered ergie refers to the smallest cross-section of the test bar at the notch. The value of impact strength is determined by the share of work needed to impact a broken pole to that of the rod at the notch (J.cm-2). In some countries (notably the U.S.) is used Izodova test, in which the outplacement casually gripping the test bar with a notch. The result is expressed only as consumed by work without conversion to gauge rods.
