The standard is frequently revised to address emerging technologies. The (ASTM E83-23) introduced Annex A1 , which specifically focuses on the verification requirements for optical extensometers, emphasizing the importance of consistent setup to account for variables that impact digital device performance. As of early 2025, the newest edition is listed as ASTM E83-25 . Critical Role in Material Testing
