See Chinese contents: YY/T 0988.14-2016 YY/T 0988.14-2016: Coatings of surgical implants--Part 14: Stereological evaluation method of porous coatings
This Part of YY/T 0988 includes stereological test methods for characterizing the coating thickness, porosity and average intercept of various porous coatings attached to non-porous substrates. Methods for measuring porosity and intercept at different levels of the and quot;tissue interface gradient and quot; in the various thicknesses of porous coatings are outlined in 9.4. The tangential sampling method in 8.2 is not applicable to the tissue interface gradient method in 9.4. This Part uses the International System of Units (SI). This Part does not attempt to describe all the security issues involved; even those security issues related to its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices, and to clarify the applicability of regulatory limitations prior to application.
