Metal Testing Equipment - Low Temperature Cooling Chambers for Charpy Impact Specimens

Low Temperature Cooling Chambers for Charpy Impact Specimens

ASTM E23, ISO 148-1

Cooling chambers play a crucial role in the accurate testing of Charpy impact specimens, ensuring the integrity and reliability of test results. "Low temperature cooling chambers for Charpy impact specimens" are essential for maintaining sample temperatures to simulate real-world conditions, which is vital for evaluating material performance under extreme cold. Torontech offers an extensive range of low temperature cooling chambers designed specifically for Charpy impact specimens, adhering to stringent standards like ASTM E23 and ISO 148-1. These standards outline the methods for conducting Charpy impact tests, emphasizing the importance of precise temperature control to achieve valid and consistent results. By providing reliable and efficient cooling solutions, Torontech ensures that your testing processes meet global standards and deliver accurate, reproducible data.

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.
