If you work internationally, you will notice that the has a cousin: ISO 9513 .

To comply with ASTM E83, a system must be verified using a calibration device (like a laser interferometer or a digital micrometer) that is significantly more accurate than the extensometer being tested. 1. Temperature Stabilization

Without ASTM E83, strain measurement would lack standardization, and material property data could become inconsistent or unrepeatable across industries and national boundaries.

: Step-by-step methods for calibrating extensometers against known reference displacements, such as calibrated micrometers or gauge block systems. astm e83 pdf

“You’re a ghost,” she muttered to the PDF. The document had no interactive calculators, no decision trees. Just dense text and a note that “verification shall be performed in at least three directions of strain.” It was written for an era when engineers smoked at their desks and used slide rules.

ASTM International holds the copyright for this standard. You can typically acquire the PDF through:

As of the publication of this article, the current active version is (approved in 2023). If you work internationally, you will notice that

The verification must take place in a temperature-controlled environment. Temperature variations can cause thermal expansion in both the extensometer and the calibration apparatus, skewing results.

The extensometer is mounted on a high-precision calibration apparatus (often called an extensometer calibrator or interferometer).

ASTM E83 is the backbone of reliable strain measurement in material science. By strictly adhering to its classification metrics and verification routines, testing facilities guarantee that their data holds up to international scrutiny. To maintain compliance, ensure your laboratory always references the official, active ASTM E83 PDF.

of the strain. Frequently used for determining modulus of elasticity. Moderate accuracy, with a maximum error of of the strain. Common in many tensile testing scenarios. Class C: Standard accuracy, with a maximum error of of the strain. Class D: Lower accuracy, with a maximum error of of the strain, used for less critical strain measurements.
