ASTM F1147-24 PDF

Full title and description

ASTM F1147-24 — Standard Test Method for Tension Testing of Calcium Phosphate and Metallic Coatings. This standard specifies a uniaxial tensile test procedure to evaluate the adhesion (or internal cohesion) of calcium phosphate and porous metallic coatings applied to dense metal substrates, producing comparative values useful for quality control, design evaluation, and R&D of implant and coating systems.

Abstract

F1147-24 describes preparation, fixturing, and uniaxial tensile loading of coated metal specimens to measure the force required to separate coating from substrate or to cause cohesive failure within the coating. The method reports adhesion/cohesion results in inch-pound units (with SI conversions for information) and notes limitations related to processing variables and representativeness of the specimen for end-use conditions.

Scope

This test method covers tension testing of calcium phosphate and metallic porous coatings adhering to dense metal substrates at ambient temperature to assess coating adhesion to substrate or the internal cohesion of the coating when stressed normal to the surface. It establishes recommended specimen configuration, tensile-fixture arrangements, and reporting conventions, while clarifying that results are comparative and sensitive to processing and surface-preparation variables.

Key topics and requirements

• Specimen preparation and representative sampling of end-use coating systems.
• Attachment/fixturing methods to transfer tensile load through the coating–substrate interface.
• Uniaxial tensile loading to measure adhesive or cohesive failure and peak separation force.
• Reporting in inch-pound units (SI conversions provided for information).
• Limitations: results are comparative and affected by substrate preparation, coating technique, surface texture, and post-coating treatments.
• Interpretation guidance — not intended as a direct predictor of environmental durability without complementary testing.

Typical use and users

Used by implant and medical-device manufacturers, coatings suppliers, contract test laboratories, R&D teams developing calcium phosphate or porous metallic coatings (e.g., plasma-sprayed hydroxyapatite), and regulatory or quality groups requiring standardized adhesion data during product development and batch verification.

FAQ

Q: What is this standard?

A: ASTM F1147-24 is a standardized test method for measuring the tensile adhesion or internal cohesion of calcium phosphate and porous metallic coatings on dense metal substrates using a uniaxial tension test.

Q: What does it cover?

A: It covers specimen preparation considerations, fixturing and tensile-loading procedures, data reporting (inch-pound units with SI conversions), and limitations on interpretation; it is intended for comparative evaluation rather than as a sole predictor of environmental durability.

Q: Who typically uses it?

A: Medical-device and implant manufacturers, coating producers, independent test laboratories, R&D and quality/validation engineers involved with implant surface coatings.

Q: Is it current or superseded?

A: Current — the F1147-24 edition is the active version released in 2024. Earlier historical editions include 2005 (with reapproval/edits) and previous versions; check your organization's standards library or ASTM for amendment/redline details when comparing editions.
