By means of our testing expertise and modular product design, asttm will help find the testing solution that is right for you. Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM F We are confident that we have what you are looking for. Consider the right grip for the job. Next, apply a shear load to each test specimen at a astmm rate of cross-head speed of 0.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
This newer version provides a means of testing and comparing different calcium phosphate thermal sprays to determine the high adhesion characteristics.
Combining values from the two systems may result in non-conformance with the standard. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.
ASTM F Shear Testing for Calcium Phosphate and Metallic Coatings
Acquire a polymeric adhesive that is capable of bonding astmm coating on the test specimen with a shear strength of at least It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique asmt. It assesses the degree of adhesion of coatings to substrates, or the internal cohesion of a coating in shear, parallel to the surface plane.
Information developed using this test method may be useful for certain quality control and design purposes. Misaligned grips can easily introduce bending stresses that are not included in the typical stress calculation. Record the maximum load applied. Calcium phosphate and metallic coatings are used on a wide variety of metal substrates around the world, and commonly on orthopedic implants.
The specimen being evaluated must be representative of the actual end-use coating. Testing Procedure Acquire a polymeric adhesive that is capable of bonding the coating on the test specimen with a shear strength of at least The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.

ASTM F1044 Shear Fixture for Testing Calcium Phosphate and Metallic Coatings | GF1044-788
Measuring the adhesive quality of these products is essential due to their direct impact on implant degradation and bioactivity. Historical Version s – view previous versions of standard. Apply the coating of interest to the face of each in the same manner as for actual production devices. ASTM F is a standard test adtm for shear testing calcium phosphate adhesion strength to metallic substrates under uniaxial shear stress.
Have a question about conducting the test for this standard? Continue the test until the components have been completely separated. Cure the adhesive agent and prepare a minimum of five test specimens.
