Assesses material or component performance under repeated cyclic loading.
When to use this
Use this when service loading is repeated and failure may occur below static strength limits.
Suitable materials
Metals, polymers, composites, welded parts and prototype components.
What to provide for a quotation
Load ratio, frequency, stress or strain level, environment, run-out criterion and sample geometry.
Typical outputs
Typical outputs include cycles to failure, S-N data, run-out confirmation and failure observations.
Standards to discuss
- ASTM E466
- ISO 1099
The applicable edition, material scope and any departures are agreed in your quotation. This guide is not a claim of accreditation or certification.
TESTDOG confirms the method, scope, price and delivery time before work starts. Sample acceptance and any preparation requirements are part of that review.
