ASTM F1044: Standard Test Method for Shear Testing of Calcium Phosphate Coatings and Metallic Coatings

This test method covers shear testing of continuous calcium phosphate coatings and metallic coatings adhering to dense metal substrates at ambient temperatures. It assesses the degree of adhesion of coatings to substrates, or the internal cohesion of a coating in shear, parallel to the surface plane.

Typically n=6 flat cylindrical, coated specimens are glued against a matching counterpart and load up to failure.

ASTM F1160: Standard Test Method for Shear and Bending Fatigue Testing of Calcium Phosphate and Metallic Medical and Composite Calcium Phosphate/ Metallic Coatings.

This test method covers the procedure for determining the shear and bending fatigue performance of calcium phosphate coatings and of porous and nonporous metallic coatings and for determining the bending fatigue performance of metallic coatings oversprayed with calcium phosphate. This test method has been established based on plasma-sprayed titanium and plasma-sprayed hydroxylapatite coatings. The efficacy of this test method for other coatings has not been established. In the shear fatigue mode, this test method evaluates the adhesive and cohesive properties of the coating on a metallic substrate. In the bending fatigue mode, this test method evaluates both the adhesion of the coating as well as the effects that the coating may have on the substrate material.
These methods are limited to testing in air at ambient temperature. These test methods are not intended for application in fatigue tests of components or devices; however, the test method which most closely replicates the actual loading configuration is preferred.
The test method corresponds to ASTM F 1044 but dynamical load conditions instead of static ones are used.  

Be aware!
Precision in Shear Testing – Why Alignment Matters

Alignment is critical! Even minor misalignments between the shear surface and load axis can introduce tensile stresses up to 50% of the shear stress, compromising test accuracy. At Endolab, we have established strict processes to ensure precise alignment and reliable testing, delivering accurate and trustworthy results for your implant evaluations.

Let us help you achieve reliable shear testing with confidence.
