The combination of Class (accuracy) and Type (gage length) fully defines the performance specification for a given extensometer system. For example, a extensometer is a medium-length device with high accuracy suitable for routine metals testing. | | Typical Applications | Key Characteristics |
| | Typical Applications | Key Characteristics | | :--- | :--- | :--- | | Class A | Highest-precision modulus determination | Very tight error limits | | Class B-1 | Precise modulus and yield strength | High accuracy for critical properties | | Class B-2 | High-accuracy strain measurement | Stricter resolution than B-1 | | Class C | General elongation measurement (yield to ultimate tensile) | Standard accuracy for most tests | | Class D | Lower accuracy for larger strains | Higher error tolerance | | Class E | General elongation at large strains (e.g., >20%) | Suitable for post-yield elongation | This article has provided that information in depth,
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:
The search for often signals a need for authoritative information on verifying and classifying extensometer systems. This article has provided that information in depth, covering the standard’s scope, classification system, verification procedures, relationship to other standards, and official purchasing channels. The six error classes (A through E) and three gage-length types (1 through 3) form the backbone of extensometer specification worldwide.
