Yes, the GenNotch 4000UPG is capable of producing notched specimens whose geometry and force-related preparation steps align with calibration practices consistent with ASTM E74, including the more stringent demands of Class AA verified range standards. Its precise machining and control systems support producing specimens whose associated force calibrations can satisfy the lower uncertainty limits demanded by Class AA.

ASTM E74 is a standard that defines practices for calibration and verification of static force-measuring instruments (such as load cells, dynamometers, and force transducers) used in materials testing machines. In the context of Class AA, instruments must maintain a lower limit factor (LLF) whose error does not exceed 0.05 % of applied force, and the verified loading range must begin at 2000 × LLF up to the full capacity. The standard ensures high accuracy and traceability to primary force standards, minimizing measurement uncertainty in critical calibration steps.
