Charpy testing impact
WebSep 14, 2024 · The specimens generally used for performing the impact test are: charpy specimen and izod specimen, both specified by ASTM E23 standard. Of these two, the type of cp (proof body) charpy type is the most used without a doubt. It is so used that the impact test is sometimes called "charpy" (pronounced with stronger sound in Y). WebCharpy impact tests for bolts may be performed at specific test temperatures. Grades L7 and L43 require testing at -66°C (-150°F) unless otherwise specified. Since passing this test can be challenging, engineers often allow Charpy testing at a temperature more consistent with use temperatures for these fasteners.
