The technician applies discrete, known displacements using the calibrator. ASTM E83 requires at least two runs of measurements. Each run must consist of at least five displacement points spread evenly across the calibrated range.
ASTM E83 categorizes extensometer systems into three types based on their gage length—the initial distance over which the strain measurement is taken:

A: Yes, provided you have verified the extensometer to the highest class required. If an extensometer is verified as Class B-1, it can be used for applications requiring Class B-2, C, D, or E, but not for Class A applications which require higher accuracy.
Discover whether a specific extensometer qualifies as Class A, B-1, B-2, C, D, or E.
: The technician applies known displacements using the calibrator and records the output from the extensometer. ASTM E83 requires a minimum of two verification runs, consisting of at least five displacement points spaced across the testing range. Given the comprehensive overview above, you may decide
ASTM E83 provides a foundational standard for verifying and classifying extensometer systems based on error magnitude, ensuring accurate measurements of material displacement during tensile or compressive testing. It establishes performance classes (A through E) and defines procedures essential for reliable material data in structural and industrial applications.

Common for plastics testing and applications requiring moderate-to-high accuracy over larger strain ranges.
: The standard can be purchased directly from astm.org as a standalone PDF download or via an annual subscription to the Annual Book of ASTM Standards (Volume 03.01). ASTM E83 requires at least two runs of measurements
The standard is titled "Standard Practice for Verification and Classification of Extensometer Systems." It provides the rules for how extensometers—tools that measure how much a material stretches or compresses—are calibrated and graded based on their accuracy. 📄 Key Document Details
While ASTM E83 does not specify a mandatory recalibration interval, industry best practices and quality system standards such as ISO/IEC 17025 generally require:
If you are looking to review or evaluate the standard (Standard Practice for Verification and Classification of Extensometer Systems), here are three "review" styles depending on whether you are assessing the document's utility, technical depth, or professional necessity. Professional/Technical Review
Many engineering firms, test labs, and universities maintain enterprise access to the ASTM Compass platform, allowing employees and students to read or print the PDF.
