NIST self-verification Charpy specimens, such as from lot LL-198 here considered, are used by companies around the world to perform an indirect verification of a Charpy impact machine in accordance with with ASTM E23 and ISO 148-2. Customers test between 5 and 7 samples and compare their average value with the reference absorbed energy from the NIST certification tests, provided in a certificate. If within the specified limits (which depend on the reference test standard), their verification can be considered successful.
