ASTM F1147: Standard Test Method for Tension Testing of Calcium Phosphate and Metallic Coatings.

This test method covers tension testing of calcium phosphate and metallic porous 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 tension normal to the surface plane.

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