ASTM C1337 establishes a standard test method for measuring the creep rupture and creep deformation of continuous fiber-reinforced advanced ceramic composites at elevated temperatures under constant uniaxial tension. The method applies to material characterization, quality assurance, generating design data, and life prediction of high-temperature structural applications. The test standard-
- Includes continuous fiber-reinforced ceramic matrix composites (CMCs).
- Measures tensile creep strain & tensile creep strain rate.
- Evaluates creep rupture life under constant tensile loading conditions.
- Works for all continuous fiber (1-D, 2-D, 3-D) architectures.
- Also applies to certain continuous fiber-reinforced glass matrix composites.
- Assists in material qualification and engineering design.
- Provides standardized elevated-temperature creep testing procedures.
What are the Uses of ASTM C1337 Testing?

Common Challenges and Troubleshooting
Accurate creep testing requires stable furnace temperatures, accurate applied loads, proper specimen alignment, and continuous strain measurement over an extended duration. Problems are usually temperature variations, misalignment, extensometer drift, oxidation at high temperature, slip in gripping, and premature failure due to machining faults. Specimen preparation, equipment calibration, and monitoring produce accurate and repeatable results.
