ASTM D430 describes test methods for how soft rubber and rubber-to-fabric composites resist dynamic fatigue from repeated flexing. To match this to your program, talk with our team.
What ASTM D430 Covers
It evaluates the resistance of rubber and rubber-fabric materials to cracking and failure under repeated flexing, relevant to belts, tyres, and flexible components.
How the Test Is Run
Specimens are flexed repeatedly in a defined machine, and the number of cycles to crack initiation or growth characterizes the dynamic fatigue resistance.
Why It Matters
Flex fatigue resistance governs the service life of flexing rubber parts; a dedicated flexing apparatus and cycle counting are used.
