ASTM F1160 Shear and Bending Fatigue of Coatings
The ASTM F1160 standard recommends tests that determine failure modes and limits of coatings, their adhesive bonding agents, and metallic substrates. The standard covers shear and bend fatigue tests on coatings made from the following materials:
- Calcium Phosphate (CaP)
- Porous and nonporous metals
- CaP/metallic composite
The coating on a medical device provides added protection and other beneficial properties to an implant’s surface. In vivo, the coating must adhere to the metallic substrate surface and withstand shear, bending, and loading forces without failure.
Rigorous Medical Device Testing
The ATS FoC offers precise testing in a controlled environment. Our ISO/IEC 17025-certified labs house sophisticated and powerful equipment for standards-based and customized testing:
- Fatigue testing – up to 55 Kip (55,000 psi), temperatures from ambient to 1000˚ C (1832˚ F)
- Tensile testing – up to 400,000 pounds, temperatures up to 1800˚ F (982˚ C)
- Bend testing – up to 90 to 180˚ bend
We test until failure or 10,000,000 cycles, anticipating a lifetime of use.
Shear and Bend Test Outcomes
Shear and bend fatigue testing determine the coating’s adhesive or cohesive properties. Bend fatigue testing also provides information on the effects of the coating on the metallic substrate.
Clients can use ASTM F1160 testing to inform their next steps, such as product redesign or submitting the product to the FDA for in vivo testing approval. Shear and bend fatigue tests help clients evaluate how different materials, shapes, stresses, and surface conditions impact the efficacy of the coating.
