    "NIST self-verification Charpy specimens, such as lot HH-200 specimens considered here, are used by laboratories around the world to perform the indirect verification of their Charpy impact machine in accordance with ASTM E23 and/or ISO 148-2. For self-verification specimens, customers test between 5 and 7 samples and compare their average value with the NIST certified reference absorbed energy, provided in a certificate that accompanies the samples. If the mean absorbed energy is within the limits specified by the applicable test standard (ASTM or ISO), the machine indirect verification can be considered successful."
