Understanding the critical importance of Charpy Impact Testing sets the stage for delving into its step-by-step procedure and intricacies – an insightful journey that demystifies this essential method for assessing material toughness. Step-by-step Procedure of a Charpy Impact Test. Performing a Charpy impact test involves several important steps. A Charpy test determines the impact toughness of metal samples by striking them with a swinging mass. The traditional test method requires measuring the difference between the height of the striker before and after impact. . (738 foot-pound) model used for experiments on high-strength steels to a table-top unit for measurements on .シャルピー衝撃試験機. シャルピー衝撃試験（シャルピーしょうげきしけん、英: Charpy impact test ）とは、切り欠きのはいった角柱状の試験片に対して高速で衝撃を与えることで試験片を破壊し、破壊するために要したエネルギーと試験片の靭性を評価するための衝撃試験である。Charpy Impact Testing . At WMT&R Izod and Charpy impact testing are performed on instrumented machines capable of measuring less than 1 ft-lbf to 300 ft-lbf at temperatures ranging from -320°F to over 2000°F. Instrumented Impact Testing . The purpose of impact testing is to measure an object's ability to resist high-rate loading.
NextGen's Class G – Servo-Motor Single Column Charpy and Izod Impact Testing system is commonly used in R&D laboratories.
