Ability of a material to absorb energy and plastically deform without fracturing is much required in materials for better toughness used in modern industry. Amount of energy per unit volume that a material can absorb before rupturing is needed to be measured, in other words keeping a balance of strength and ductility, higher the material's resistance to fracture when stressed tougher the material. 

The Charpy impact test, also known as the Charpy V-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. This absorbed energy is a measure of a given material's notch toughness and acts as a tool to study temperature-dependent ductile-brittle transition. It is widely applied in industry, since it is easy to prepare and conduct and results can be obtained quickly and cheaply. 

Torontech’s TTIC low-temperature chamber for cooling samples for impact testing is newly researched and developed compressor refrigeration unit according to low temperature device Metallic materials-Charpy notch impact test requirements. This device uses overlapping compressor refrigeration technique and thermal equilibrium principle and cycle stir, to make the specimen.
