ISO 3800 is the test-methods standard for the axial-load fatigue testing of threaded fasteners under fluctuating tension. To match this to your program, talk with our team.
What ISO 3800 Covers
It defines how bolts, screws, and studs are fatigue tested under fluctuating axial load and how the results are evaluated, supporting design validation and supplier qualification.
How the Test Is Run
A fastener is cycled under a defined mean and alternating axial load until failure or run-out, and the fatigue life or strength is evaluated per the method.
Why It Matters
Fatigue performance governs fastener durability under repeated tension; a fatigue-rated axial machine and precise alignment are essential.
