Each class corresponds to a specific maximum permissible error expressed as a percentage of strain. The lower the class letter (A being highest), the smaller the allowable error.

ASTM E83 is a standard practice established by ASTM International. It outlines the procedures for the verification and classification of extensometer systems.
This article delves into the core of ASTM E83, exploring the technical requirements for verifying extensometer systems, its classification framework, and importantly, how to access the official standard document for your own laboratory or quality control processes. astm e83 pdf
Many manufacturing industries (aerospace, automotive, medical devices) require ISO or ASTM compliance to sell products.
The primary purpose of this standard is to provide systematic procedures for the calibration, verification, and subsequent classification of extensometers. By establishing strict accuracy thresholds, ASTM E83 ensures that data collected across different laboratories, industries, and countries remains consistent, reliable, and legally defensible.

According to the standard guidelines, verification must occur: At a minimum of once every 12 months. Each class corresponds to a specific maximum permissible
This article provides a comprehensive overview of the ASTM E83 standard, explains the importance of obtaining the official PDF, and outlines the key classes used to classify extensometer performance. What is the ASTM E83 Standard?
Note: While classes C through E have the same maximum error percentage, they may differ in other performance criteria such as resolution or linearity. Importance of Accurate Strain Measurement Standard ASTM E83-25 - Afnor EDITIONS
The standard requires applying known displacements at multiple intervals across the extensometer’s working range. Typically, at least two verification runs are performed to ensure repeatability. ASTM E83 is a standard practice established by

: It applies to both contacting and non-contacting (optical/video) extensometers and is compatible with both SI and US customary units because strain is a dimensionless quantity. Recent Updates (ASTM E83-23/25)
