In its most common form (notched specimen . the U.S. infrastructure up to safe standards.There are ISO product, method, and instrument standards for impact tests with pendulum impact testers. . which has also earned these machines the designation of Charpy impact testers or Charpy impact testing machines. .
Abstract. This paper is focused on the approximation of absorbed Charpy impact energy-temperature curves (KV-T) and the management of sub-size test piece results in Charpy pendulum impact tests. Both subjects are frequently underestimated but may have a strong impact on the assessment of product quality and structural integrity. The status of related test .
Both methods characterize the impact strength of a material in very similar ways so that the results largely correlate. The Izod test method, in which the specimen is positioned vertically, is normally used in ASTM standards.; The Charpy .The Charpy impact test is still used throughout sectors to assess material toughness, from construction and manufacturing to engineering and beyond. This test offers practical insights into how materials respond to sudden, dynamic impacts. Even as businesses change, the Charpy impact test is still a valuable and essential tool.Charpy to ISO 179-1 is the preferred test method on plastics within the standard for single-point data ISO 10350-1. The test is ideally performed on unnotched specimens with edgewise impact (1eU). Should the specimen not break during the test, any subsequent tests are performed with notched specimens. Similarly, the Charpy impact test is governed by standards such as ASTM E23 and ISO 148. These standards provide guidelines for the preparation of notched specimens, the pendulum's energy, and the testing environment. The results are also expressed in joules or foot-pounds, providing valuable data on the material's toughness and impact .

The Charpy impact test, also commonly referred to as the Charpy V-notch test by material scientists, serves as a standardized high-strain rate examination to quantify the energy absorbed by a material upon fracture. The absorbed energy functions as an indicator of the material’s notch toughness.
The resulting test sample measures 80 x 10 x 4 mm. The depth under the notch of the specimen is 8mm. Data: ASTM impact energy is expressed in J/m or ft-lb/in. Impact strength is calculated by dividing impact energy in J (or ft-lb) by the thickness of the specimen. The test result is typically the average of 5 specimens.
