HG-3915B simply supported beam impact testing machine

One Product Description: The simply supported beam impact testing machine is used to determine the impact toughness of non-metallic materials such as hard plastics, fiberglass, cast stone, reinforced nylon, ceramics, and electrical insulation materials. It has the characteristics of reasonable structure, beautiful appearance, convenient operation, and accurate data. After the test is completed, the energy value of the material, that is, the impact strength, can be directly read on the surface plate. Compliant with ISO 179, GB/T 1043, GB/T 2612, JB/T 8762, GB4742 and other standards for impact testing of simply supported beams. II Specification of simply supported beam impact testing machine: Impact capacity: 7.5J, 15J, 25J, 50J; Pendulum torque: 7.5J pendulum PL=3.866Nm, 15J pendulum PL=7.733Nm, 25J pendulum PL=12.889Nm, 50J pendulum PL=25.777Nm; Impact speed: 3.8m/s; Swing angle: 150 °; Minimum division value of the dial: 1%; Distance from the center of the pendulum to the center of the specimen: 380mm; Jaw corner radius: R=1 ± 0.1mm; Blade fillet radius: R=2 ± 0.5mm; Impact blade angle: 30 ± l °; Distance between jaw support lines: 40mm, 60mm, 70mm, 95mm; Energy loss of pendulum impact: 0.5%; The sample type, size, and support distance are shown in the table below (please refer to GB/T1043-93 for test type and size) in millimeters.
