, which specifically addresses the verification requirements for optical (non-contacting) extensometers . This update emphasizes: Setup Consistency:

Ensuring that strain measurements are consistent, regardless of the laboratory or instrument used. ASTM E83 Extensometer Classifications

: Laboratories seeking or maintaining ISO/IEC 17025 accreditation must prove their testing machines and extensometers are calibrated to a recognized national or international standard. astm e83 pdf

The verification process outlined in the ASTM E83 PDF involves comparing the readings of the extensometer against a highly accurate reference device, known as a calibration apparatus or displacement standard. Key Steps in the Verification Procedure:

Material testing data is only as good as the measurement tools used. ASTM E83 addresses several key aspects of measurement quality: The verification process outlined in the ASTM E83

Outlines procedures to verify that an extensometer's indicated values are proportional to actual changes in specimen length. Classification: Systems are categorized (e.g., Class A, B-1, B-2, C, D, E ) based on the magnitude of their measurement errors. Applicability:

ASTM E83 is a standard practice published by ASTM International. Its official title is Classification: Systems are categorized (e

Detail the exact manufacturer, model, and serial number of the extensometer system.

The standard is managed by ASTM Subcommittee E28.01 on Calibration of Mechanical Testing Machines and Apparatus. It is regularly updated to adapt to evolving technological trends in manufacturing and testing engineering:
