ASTM E83 is a standard practice that outlines the procedures for the verification and classification of extensometer systems. It establishes a strict methodology to determine the maximum permissible error for instruments used to measure axial strain during tension, compression, or fatigue testing.

The physical calibration must be performed using a certified verification apparatus (often called an extensometer calibrator or micrometer tower). This apparatus must be highly accurate—typically traceable to national standards like NIST—and must have an accuracy at least five times greater than the extensometer being verified. Step-by-Step Verification Procedure ASTM E83 is a standard practice that outlines

: Because strain is a dimensionless ratio (change in length divided by original length), the ASTM E83 protocol seamlessly supports both SI metric units (millimeters) and U.S. Customary units (inches). The tensile test began

The tensile test began. The steel yielded at 485 MPa, right where it should. The extensometer, now a faithful servant, delivered the 0.2% offset data without complaint.
