Low-Energy Charpy V-Notch specimens (NIST-verification, 8 mm striker) are standardized test specimens designed to verify the accuracy and calibration of Charpy impact testing machines, specifically within the low-energy range. These specimens are crucial for ensuring the reliability and consistency of impact toughness measurements in materials testing laboratories and industrial settings.  

These specimens conform to the internationally recognized Charpy V-notch impact test standard, which involves fracturing a notched specimen with a swinging pendulum to determine the material's resistance to impact. The "V-notch" refers to the precise 45-degree notch machined into the specimen, creating a stress concentration that promotes brittle fracture.

A key feature of these specimens is their "Low-Energy" designation. This indicates that they are specifically designed for verifying impact testing machines at lower energy levels, where accuracy can be critical. This ensures that the machines provide reliable results within a specific, often lower, energy range.  

"NIST-verification" signifies that these specimens are certified by the National Institute of Standards and Technology (NIST). This certification ensures traceability to national standards, providing confidence in the accuracy and reliability of the specimen's impact energy values. NIST verification is essential for laboratories seeking accreditation and for maintaining quality control in critical applications.  

The "8 mm striker" specification indicates that these specimens are designed to be used with an impact testing machine equipped with an 8 mm striker tip radius, a standard dimension in Charpy impact testing.
