WebMar 12, 2024 · Based on ASTM A370/ISO 148, the standard Charpy impact test specimen size is 10 mm × 10 mm × 55 mm. The Charpy impact test is executed on both notched or unnotched specimens. However, the notched specimen is the most widely used Charpy test specimen. Again, there are two types of notches; V-notch and U-notch. WebOne of the main differences from Charpy impact is that Izod impact testing can be performed on either plastic or metallic specimens. Plastic samples are typically a 64 x 12.7 x 3.2 mm bar with a machined V-shaped notch. Metallic samples are typically round 127 x 11.43 mm bar with 1 or 3 machined V-shaped notch (es). mass insight staff https://yangconsultant.com
