ASTM E83-23 outlines the standard practice for verifying and classifying extensometer systems used in materials testing, assigning performance classes from A to C based on measurement accuracy. The standard, which mandates regular, typically annual calibration, covers both contact and optical devices, with the latest revision adding specific requirements for non-contact systems. Official copies of the standard can be purchased directly from the ASTM International Store 分析测试百科网 Verification and Classification of Extensometer Systems1

"I need time on the laser extensometer in the grad wing," she said. "And I need to redo my verification runs per E83, section 7.2.1." ASTM E83-23 outlines the standard practice for verifying

Some of the key benefits of using ASTM E83 include: Verification of Performance: It establishes a protocol to

Application: Essential for laboratories performing mechanical testing to ensure compliance with material specifications like ASTM E8 (tensile testing of metals).

• Verification of Performance: It establishes a protocol to verify that an extensometer performs according to manufacturer specifications or user requirements.
• Classification System: It defines distinct classes of performance (Class A, B, C, etc.). This allows a test engineer to select an extensometer with the appropriate level of precision for the material being tested (e.g., testing brittle ceramics requires a higher class than testing ductile rubber).
• Traceability: The verification process requires the use of reference standards (such as calibrated micrometers or interferometers) that are traceable to national standards (like NIST), ensuring the chain of calibration is unbroken.
