ASTM E83 is a fundamental technical standard used by engineers, labs, and manufacturers to ensure the accuracy of extensometers. These devices are critical for measuring the strain and deformation of materials during mechanical testing.
The verification must be performed using a device capable of applying known displacements. Common devices include: astm e83 pdf
In short, ASTM E83 provides the roadmap for verifying and classifying the instruments we use to measure how much a material stretches or compresses under load. It ensures that the extensometer you’re using—whether it's a traditional clip-on gage or a high-tech optical system—is actually telling you the truth.

Without that PDF, you wouldn’t know the correct verification fixture size or the acceptable error margins. Laboratories should obtain a copy of the ASTM
