ASTM WK24374

    Work Item: ASTM WK24374 - New Guide for determining Darcy permeability coefficients for porous tissue scaffolds.

    (What is a Work Item?)

    Developed by Subcommittee: F04.42 | Committee F04 | Contact Staff Manager



    1. Scope

    1.1.This guide describes test methods suitable for determining the Darcy permeability coefficient for a porous tissue scaffold, which is a measure of the rate at which a fluid, typically air or water, flows through it in response to an applied pressure gradient. This information can be used to optimize the structure of potential tissue scaffold, to develop a consistent manufacturing process and for quality assurance purposes. 1.2.The method is generally non-destructive and non-contaminating. 1.3. The method is not suitable for structures that are easily deformed or damaged. Some experimentation is usually required to assess the suitability of permeability testing for a particular material/structure and to optimize the experimental conditions. 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
