An instrument is only granted a classification if its performance stays within both boundaries across its entire calibrated range. How the Verification Process Works

For engineers, technicians, and quality control managers, having access to the is essential for maintaining compliance with testing standards like ASTM E8 (tension testing of metals). This article provides a comprehensive overview of the standard, its classifications, and how to verify extensometers. What is ASTM E83?

To verify an extensometer, labs use an apparatus capable of introducing precisely known displacements. This calibration device itself must be calibrated and traceable to a national metrology institute, such as the National Institute of Standards and Technology (NIST), and must have an accuracy significantly higher than the extensometer being tested. 3.

The Ultimate Guide to ASTM E83: Standard Practice for Verification and Classification of Extracyclic and Extensometer Systems

Applies at larger displacements where the error is calculated as a percentage of the actual reading. What is ASTM E83

When searching for an , it is crucial to understand that downloading unauthorized, bootleg, or outdated copies can jeopardize your laboratory's accreditation. Risks of Using Outdated or Unofficial Documents

Explains the strict accuracy requirements of the calibrator itself. The calibrator must generally be 5 times more accurate than the class of extensometer being verified.

It does not cover bonded resistance strain gages, which are instead addressed under Key Performance Classes

Utilizing a universally accepted verification standard ensures that a material tested in Asia, Europe, or North America yields identical, comparable data.
