Key Aspects of ASTM E83 E83 Standard Practice for Calibration, Verification

, titled the "Standard Practice for Verification and Classification of Extensometer Systems," provides the fundamental framework for ensuring that devices used to measure strain in materials—such as those used in tensile and compression testing—are accurate and reliable. The standard is essential for laboratories to maintain traceability to international measurement systems, ensuring that data produced in one facility is comparable and verifiable by others, such as customers or quality assurance auditors. Key Functions and Scope ASTM E83 is a verification standard, not a

Technicians take readings at various increments across the extensometer's range. This ensures accuracy at both small strains (near zero) and large deformations. 3. Reporting Results A verification report must include: The date of calibration. The specific classification achieved (e.g., Class B-1). The temperature during the test. The traceability of the calibration equipment. 📈 Why You Need the Official PDF
