Information on the most widely used ASTM standards within the materials testing industry
ASTM C633, ASTM F1160, ASTM F1147
ASTM F1147 is a standard test method for ambient-temperature tensile testing of calcium phosphate and metallic porous coatings on dense metal substrates, Its core purpose is to evaluate the adhesion strength between coatings and substrates and the internal cohesion strength of coatings under uniaxial tensile stress normal to the coating surface plane.
Coating static tensile strength tests are conducted with reference to ASTM F1047 to evaluate the adhesion of continuous calcium phosphate coatings or metal coatings to the substrate, or the bonding strength between coatings. Manufacturers should determine the tensile strength of the coating based on the type of coating, with reference to similar products and standards. As specified in FDA guidance documents, the static tensile strength at the interface between a metal coating and the substrate should not be less than 22 MPa; ISO 13779-2 specifies that the bonding strength of hydroxyapatite coatings to the substrate should not be less than 15 MPa.
General introduction
ASTM F1147 is a standard test method for ambient-temperature tensile testing of calcium phosphate and metallic porous coatings on dense metal substrates, Its core purpose is to evaluate the adhesion strength between coatings and substrates and the internal cohesion strength of coatings under uniaxial tensile stress normal to the coating surface plane.
Coating static tensile strength tests are conducted with reference to ASTM F1047 to evaluate the adhesion of continuous calcium phosphate coatings or metal coatings to the substrate, or the bonding strength between coatings. Manufacturers should determine the tensile strength of the coating based on the type of coating, with reference to similar products and standards. As specified in FDA guidance documents, the static tensile strength at the interface between a metal coating and the substrate should not be less than 22 MPa; ISO 13779-2 specifies that the bonding strength of hydroxyapatite coatings to the substrate should not be less than 15 MPa.
Test Principle of ASTM F1147
The core principle of ASTM F1147 is to subject an assembled specimen (one coated + one/more uncoated dense metal components) to pure axial tensile load perpendicular to the coating’s surface plane, eliminating eccentric loading and bending stresses that would skew results. A tensile testing machine applies load at a constant rate until the specimen assembly fully separates. The maximum failure load is recorded, and coating adhesion/cohesion strength is calculated using the formula:
S= F / A
S = Adhesion/cohesion tensile strength (MPa/psi)
F = Maximum load to failure (N/lbf)
A = Cross-sectional area of the coated substrate (measured to the nearest 0.006 cm²/0.001 in²)
This principle quantifies the ability of coatings to resist tensile forces that pull the coating away from the substrate (adhesion) or cause internal coating fracture (cohesion).
Specific Test Methods
The standard primarily describes one core tensile test method, with variations in how the test assembly is created:
Bonded Assembly Method: A test specimen assembly is created by bonding a coated component to an uncoated counterpart.
For calcium phosphate coatings, the components must be bonded together using a polymeric adhesive.
For metallic coatings, the components may be bonded with an adhesive or sintered together.
The adhesive, if used, must have a minimum bulk tensile strength of 34.5 MPa (5000 psi) or be as strong as the minimum required strength of the coating, whichever is greater.

ASTM F1147 Standard Test Method for Tension Testing of Calcium Phosphate and Metallic Coatings
ASTM F1044 is a standard procedure for determining the tensile adhesion or cohesion strength of coatings on metallic substrates. It is specifically designed for continuous calcium phosphate coatings (e.g., hydroxyapatite) and metallic porous coatings bonded to dense metal substrates. The test applies a uniaxial tensile load perpendicular (normal) to the coating plane to evaluate the integrity of the bond between the coating and substrate (adhesion) or the strength within the coating material itself (cohesion).
ASTM F2068: Standard Specification for Femoral Prostheses – Metallic Implants
ASTM F2068 covers metallic stemmed femoral prostheses used to replace the natural hip joint by means of hemi-arthroplasty or total hip surgical procedures. Prostheses for hemi-arthroplasty are intended to articulate with the natural acetabulum of the patient. Prostheses for total hip replacement are intended to articulate with prosthetic acetabular cups. Prostheses may have integral femoral heads or cones designed to accept modular heads.
The mechanical strength (fatigue test ISO 7206-4, ISO 7206-6, shear strength test ASTM F1044, tensile test ASTM F1147, abrasion resistance test ASTM F1978), corrosion resistance, and biocompatibility of the head portions of one-piece integral implants are covered by this specification.
ASTM F1160 Standard Test Method for Shear and Bending Fatigue Testing of Calcium Phosphate and Metallic Medical and Composite Calcium Phosphate/Metallic Coatings;
Rotating beam fatigue testing generates higher frequencies than traditional high cycle fatigue (HCF) methods. UnitedTest testing services provide critical data about coatings and metallic surface treatments to ISO 1143, ASTM F1160 standards.
Rotating beam fatigue testing, Shear and Bending Fatigue testing.
Rotating beam fatigue testing is a mechanical test method used to evaluate the fatigue properties of materials. In this test, a beam specimen is subjected to cyclic loading, which induces repeated bending causing failure over time. The specimen is mounted on a rotating apparatus, which allows for the cyclic load to be applied at constant amplitude and frequency.
During the test, the beam specimen is rotated at a constant speed while a loading force is applied to it. The force causes the beam to bend, and as the beam rotates, it undergoes cyclic bending stress that can induce fatigue failure.
