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.
The classification is determined by two main metrics during verification:
The 2023 revision of the standard, , includes vital updates regarding non-contacting optical extensometers (e.g., AVE3).
To ensure extensometer systems provide accurate and consistent data, allowing for reliable strain measurement in material characterization, R&D, and quality control.
ASTM E83 interacts with several other ASTM standards. Understanding these relationships helps clarify its role: astm e83 pdf
Understanding ASTM E83: The Standard Practice for Verification and Classification of Extensometer Systems
The search for often signals a need for authoritative information on verifying and classifying extensometer systems. This article has provided that information in depth, covering the standard’s scope, classification system, verification procedures, relationship to other standards, and official purchasing channels. The six error classes (A through E) and three gage-length types (1 through 3) form the backbone of extensometer specification worldwide.
Once you have the official ASTM E83 PDF, keep these practical tips in mind:
What (e.g., metals, composites, plastics) are you testing? A: Yes, provided you have verified the extensometer
Contains sample calculations and statistical formulas for determining uncertainty in your measurements. A Note on Copyright and Legal Access
When you open the ASTM E83 PDF, you will typically find these main sections:
Beyond error classes, ASTM E83 further categorizes extensometer systems into three according to gage length:
As of 2026, the most current version of the standard is ASTM E83-25 "Standard Practice for Calibration, Verification, and Classification of Extensometer Systems," a 2025 edition that explicitly includes "calibration" in its title to reflect modern practices. The previous version, ASTM E83-23, is now historical. This article has provided that information in depth,
