Historical Standard: ASTM F1854-98 Standard Test Method for Stereological Evaluation of Porous Coatings on Medical Implants
SUPERSEDED (see Active link, below)
ASTM F1854
1. Scope
1.1 This test method covers stereological test methods for characterizing the coating thickness, void content, and mean intercept length of various porous coatings adhering to nonporous substrates.
1.2 Porous coatings with significant gradients in the porosity from the substrate to the surface will require use of the alternate sample orientation method outlined in 8.2.
1.3 The values stated in SI units are to be regarded as the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
