YY/T 1982-2025 Implants for surgery—Test method for morphological characteristics of porous structures

Scope

This document describes the experimental methods for characterizing the morphological features of porous structures in surgical implants, including parameters such as porosity, pore size, wire diameter, internal connectivity, pore gradient, porous structure thickness, and internal structural defects. This document is applicable to porous structures in surgical implants. The materials covered by this document may include: - Metals, such as titanium, tantalum, magnesium, and their alloys; - Ceramics, such as hydroxyapatite and β-tricalcium phosphate; - Polymer materials (degradable or non-degradable), such as polyethylene, polyetheretherketone, polylactic acid, or polycaprolactone; - Composite materials. The manufacturing techniques covered by this document may include, but are not limited to: - Additive manufacturing; - Adding foaming agents; - Template method; - Gas pore formation method; - Vapor deposition method, etc. This document is not applicable to various porous coatings attached to non-porous substrates specified in YY/T 0988.14, such as plasma sprayed pure titanium coatings, plasma sprayed hydroxyapatite coatings, and sintered coatings formed by thermally polymerizing individual entities (powder particles, metal wires, meshes, beads, etc.). Note: Users of this document can select appropriate experimental items based on the test samples and manufacturing techniques.
