The position of the pendulum holding and releasing mechanism with the vertical height of fall of the striker at 610 ± 2 mm? The effective length of the pendulum between 0.33 and 0.40 m? The machine provided with a basic pendulum capable of delivering an energy of 2.7 ± 0.14 J within ± 0.5 % of its nominal capacity? A vise to clamp the specimen rigidly in position? The striking surface comes within 0.2 % of scale of touching the front face of a standard specimen when the pendulum is free hanging? Means provided for determining the energy expended by the pendulum in breaking the specimen? The vise, pendulum, and frame shall be sufficiently rigid to maintain correct alignment of the hammer and specimen? The base shall be sufficiently massive that the impact will not cause it to move? A check of the calibration Micrometers To measure the width of the specimen and the depth of plastic – material remaining in the specimen under the notch Comments: • Izod Pendulum Impact Resistance – Test Method E: Cantilever Beam Reversed Notch Test Izod Pendulum Impact Resistance (Test Method E: Cantilever Beam Yes No Reversed Notch Test) B) Procedure (ASTM D 256 Sec. 29.0) At least five and preferably ten or more individual determinations of impact resistance on each sample? Specimens with the same nominal width (±0.3 mm)? Lightest standard pendulum that is expected to break each specimen in the group with a loss of not more than 85% of its energy? Machine with the proper pendulum in place for conformity with the requirements of Section 6 before starting the tests? Proper correction for windage and friction?
