The classification is determined by evaluating the system's error against the following limits (summarized from the official standard matrix): Classification Maximum Error of Strain Reading (Whichever is greater) Max. Error of Gage Length ±plus or minus 0.1% of value OR ±plus or minus 0.00001 in. (0.00025 mm) ±plus or minus 0.25% of length Class B-1 ±plus or minus 0.5% of value OR ±plus or minus 0.0001 in. (0.0025 mm) ±plus or minus 0.50% of length Class B-2 ±plus or minus 0.5% of value OR ±plus or minus 0.0002 in. (0.0050 mm) ±plus or minus 0.50% of length Class C ±plus or minus 1.0% of value OR ±plus or minus 0.001 in. (0.025 mm) ±plus or minus 1.00% of length Why Laboratories Search for the ASTM E83 PDF
Some of the key benefits of using ASTM E83 include:
ASTM E83 is a standard practice that provides guidelines for the verification and classification of extensometer systems used in materials testing. Extensometers are instruments that measure the deformation of materials under load, and their accuracy is crucial in determining the mechanical properties of materials. This guide provides an overview of the ASTM E83 standard, its significance, and a step-by-step guide on how to verify and classify extensometer systems.
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? astm e83 pdf
: This involves applying a series of controlled displacements to an extensometer using a calibrated apparatus (extensometer calibrator) and comparing the device's output to the reference.

Closing the file, the reader was left with two impressions. First, a technical satisfaction—the comfort of knowing what to do next, step-by-step, when faced with a measuring device that must be known. Second, a quieter recognition: standards like this are the scaffolding of modern trust, small, exacting agreements that let commerce, safety, and science proceed without daily argument over the length of things. The PDF, austere and careful, was less a document than a pact—an act of collective craftsmanship that made precision possible. E83 Standard Practice for Calibration, Verification
Many engineering firms and academic institutions maintain institutional subscriptions to the ASTM Compass platform, giving employees and students free access.

To ensure these measurements are globally consistent and accurate, the American Society for Testing and Materials (ASTM) established . This standard practice defines how to verify and classify extensometer systems. systems must undergo regular re-verification.

An ASTM E83 certification is not permanent. To maintain compliance with quality management systems like ISO 9001, AS9100, or Nadcap, systems must undergo regular re-verification.
