After researching different polymers and comparing mechanical properties it was found that Polypropylene polymer was mainly used in manufacturing of bumpers. The Izod impact strength testing described by E. G. Izod 7 is an ASTM 8 method. BY 1933, the American Society for Testing and Materials (ASTM) had developed a standard, E231, to be used for Charpy impact testing. It is a guideline that companies use to make decisions concerning how much earnings will be paid to shareholders. The Charpy impact test was invented in 1900 by Georges Augustin Albert Charpy (18651945), and it is regarded as one of the most commonly used test to evaluate the relative toughness of a material in a fast and economic way. The figure below, from Mitsubishi Chemical Advanced Materials, depicts the Izod impact strength test apparatus.

These impact tests allow designers to compare the relative impact resistance under controlled laboratory conditions and, consequently, are often used for material selection or quality control. Harmony. Pendulum Charpy/Izod Impact Testing is a high strain-rate test to determine the amount of energy absorbed by a material during fracture.The Impact tester involves a pendulum of known mass and length which is dropped from a known height to strike an Impact Specimen. The impact test helps measure the amount of energy absorbed by the specimen during fracture. To carry out this test we have prepare specimen as per the standards. It is a way to teach learning prioritization. Gaskell, David R. (1995). The Charpy piece is supported horizontally between two anvils and the pendulum strikes opposite the notch, as shown in figure 7-67, view A. The most common specimen thickness is 3.2mm (0.13in), but the width can vary between 3.0 and 12.7mm (0.12 and 0.50in). were also in use. Calibration standard is required. Since wear is always a result of abrasion, different test methods have been developed for the simulation of long-term wear. It has an intelligent power failure recovery system. The system is capable of taking a hardness value while a temperature sensor mounted on the bottom of the device is taking a temperature value.

The striker swings downwards impacting the test piece at the bottom of its swing. The problem is, while these companies may appear to be helping the environment in the short term, what many fail to address is how they plan on being environmentally conscious in the long run, in other words, how to be sustainable. They are then immediately removed and tested within seconds of removal from the freezer. Charpy and Izod Impact Testing Unit. A notched specimen then gets secured on a support anvil in the lower part of the machine. Metallic samples are typically round 127 x 11.43 mm bar with 1 or 3 machined V-shaped notch (es). Mechanical testing services are a long-established mainstay of the business, and Rotech has a large, well-equipped sample preparation workshop and test house facility. The Izod impact method can test for the toughness of metallic as well as plastic materials. Izod test One of two tests that may be used to measure the impact energy of a standard notched specimen.

The ASTM method for izod Impact is D 256. ASTM E2298 this standard is for instrumented impact testing of metallic materials. Specimen Dimensions The basic specimen size for Izod tests is 63.5 x 12.7 x 3.2 mm bar (for plastics) and 127 x 11.43 mm (round metal bar) The specimen in the Pendulum Charpy impact tester is a horizontal beam secured on both ends, while the specimen for the Izod impact tester is cantilevered in a vertical position. The plunger is then released onto the specimen for a given number of impacts. Izod tests are often performed on an instrumented machine with a weighted pendulum. Tough materials absorb a lot of energy, whilst brittle materials tend to absorb very little energy prior to fracture.
