ASTM E23 Metallic Materials Notched Rod Impact Test

Developed by the American Testing and Materials Agency (ASTM), the ASTM E23 standard describes one of the standard testing methods applied for impact testing of metallic materials. The full name of the standard is as follows: ASTM E23 Notched bar impact test of metallic materials.

The ASTM E23 standard describes the Charpy test and Izod tests, one of the notched bar impact tests that determine the energy absorbed by metallic materials during breakage. These tests are carried out at various temperatures. Absorbed energy is a measure of the toughness of the material and is used to determine changes in energy absorbed in the fracture at various temperatures.

The properties determined by the notched bar impact test method of ASTM E23 Metallic materials relate to the behavior patterns of a material, especially a metal material, which is subjected to a single force application that causes multi-axis stresses associated with a notch.

The test method explained to the ISO 23-148 standard with the ASTM E1 test method shows many similarities. While this method uses a 2 or 2,5 millimeter radius hammer, the 148-1 standard uses a 2 or 8 millimeter hammer. However, although these tests use the same test sample and lock radius, the samples are tested on different machines that have been calibrated to different reference standards.

In some sectors, the resistance of the material against sudden impacts is an important criterion. Therefore, material selection is important and the resistance of the material against breaking is tested and measured. Many testing methods, including the Charpy notch test, have therefore been developed. In the materials used in production, as well as design errors, workmanship and production errors cause the formation of notches, increased tension and reduced toughness.There maker.
