ASTM F1854 : 25

Standard Test Method for Stereological Evaluation of Porous Coatings on Medical Implants Using Digital Images

Standard Details

1.1 This test method covers stereological test methods for characterizing the thickness, void content, and mean intercept length of various porous coatings either in bulk form or adhering to non-porous substrates.

1.2 A method to measure void content and intercept length at distinct levels (“Tissue Interface Gradients”) through the porous thickness is outlined in 9.4.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
