The tests are normally performed in normal climate or at low temperatures. Applications include: The comparison of different molding materialsThis page introduces the Charpy impact test principle and methods; as well as evaluation methods, test piece standards, differences from the Izod impact strength test, and methods for measurement of the fracture surface. The 3D Solutions Library operated by KEYENCE introduces examples of shape measurement problems and the latest solutions for various industries, .
The Charpy impact specimens of each material are immersed in a bath for 10 minu tes to reach thermal equilibrium at five separate temperatures ranging from 110oF (-79oC) to 212-oF (100oC). The specimens are quickly transferred to the Charpy testing machine, fractured, and the impact energy is measured. AfterThe outer dimensions of specimens to ASTM D256 are specified to a length of 2.5 in (63.5 mm) and a height of 0.5 in (12.5 mm). The width of injection molded specimens may be between 0.118 in (3.0 mm) and 0.5 in (12.5 mm), whereby the use of specimens with a width of 1/8 in (3.2 mm) or 1/4 in (6.35 mm) is common. .

Materials – Charpy Pendulum Impact Test – Part 1: Test Method,7 consists of a physical part (direct verification) and an experimental part (indirect verification). The direct verification consists in the detailed evaluation of machine dimensions, alignment, and other physical quantities and variables. The indirect verification requiresV-notch Charpy impact test has been widely used to qualify toughness of steels and welds (e.g., [5, 6]). In this work, instrumented Charpy tests of pre-charged steel specimens were conducted at ambient temperature using a pendulum machine with a capacity of 750 J. Two to three repetitive specimens were tested for each pre-charging condition.Charpy specimens according ASTM E23-02a were manufactured. Figure 5 shows the dimensions of machined specimens. The toughness impact tests were carried out in a Rosand V1.01 machine (Rosand .Charpy Impact Test Specimen Dimensions. A Charpy test specimen, which is placed horizontally into the machine, is typically a 55 x 10 x 10mm (2.165" x 0.394" x 0.394") bar with a notch machined into one of the faces. This notch, which can be either V-shaped or U-shaped, is placed facing away from the pendulum and helps to concentrate the stress .
The Charpy impact test, also known as the Charpy V-notch impact test, measures the energy a material absorbs when it fractures under an impact load. A pendulum in a Charpy impact test machine is released to strike a notched specimen, and the amount of energy absorbed during the break is calculated.
Charpy Impact is a single point test that measures a materials resistance to impact from a swinging pendulum. Charpy impact is defined as the kinetic energy needed to initiate fracture and continue the fracture until the specimen is broken. The values obtained can be used for quality control or to differentiate general toughness. Test Procedure:ASTM A370 is one of the most broadly recognized and encompassing standards for measuring the tensile strength of metals.This guide is designed to introduce you to the basic elements of an ASTM A370 tensile test and provide an overview of the testing equipment, software, and specimens needed. In addition to tension tests, the standard also outlines charpy impact, . A total of 7 specimens for Charpy impact test were obtained by cutting each composite plates according to ASTM D6110 dimensions [28]. The tests were performed in a PANTEC instrumented pendulum, Model XC-50, 1 × 220 V × 60 Hz. Fig. 3 illustrates the prepared specimens for the Charpy tests. Download : Download high-res image (294KB)
