Commercial Fluid Power can help with your Charpy test requirements. Charpy impact testing is a standardized test which determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's toughness. This test is often used as one factor in determining a material's suitability to be used in a cold weather application.

This test was developed in 1905 by the French scientist Georges Charpy and was a key component in understanding the fracture problems of ships during the early 1900's such as the Titanic. Today this is a common test for cylinders.

An impact test consists of a pendulum axe swinging at a notched sample of material. The energy transferred to the material can be determined by comparing the difference in the height of the hammer before and after a fracture. 

ASTM E23 which is the "Test Methods for Notched Bar Impact Testing of Metallic Materials" and ASTM A370 which is "Standard Test Methods and Definitions for Mechanical Testing of Steel Products" these standards contain details needed for certified impact testing.

Commercial Fluid Power can meet your material certification requirements.  Mechanical testing, chemistry, impact and corrosion resistance testing are just a few of the common material certification Commercial Fluid Power can offer our Customers.
