The standard applies to any instrument that indicates or records values proportional to changes in length caused by either tensile or compressive strain. It is relevant across numerous industries, including aerospace, automotive, construction, metallurgy, and plastics manufacturing, wherever precise material property testing is required.

The process of verifying an extensometer to ASTM E83 is a rigorous calibration procedure. Meeting industry standards for accreditation (e

Typically required for determining high-precision properties like Young's Modulus (modulus of elasticity).

The classification is determined by two main metrics during verification:

ASTM E83-23 outlines the standard practice for verifying and classifying extensometer systems used in materials testing, assigning performance classes from A to C based on measurement accuracy. The standard, which mandates regular, typically annual calibration, covers both contact and optical devices, with the latest revision adding specific requirements for non-contact systems.
