ASTM E2109-01, "Standard Test Methods for Determining Area Percentage Porosity in Thermal Sprayed Coatings," outlines methods for assessing coating quality via direct comparison or automated image analysis. It provides protocols for quantifying porosity, which impacts corrosion resistance and structural integrity in thermal sprayed coatings. To purchase or view the full standard, visit ASTM International.

The document provides high-magnification examples of properly prepared specimens (up to 500X) to help identify these artifacts. If there is doubt about a sample's integrity, the standard suggests using advanced techniques like , or cryogenic fracture followed by scanning electron microscope (SEM) analysis for confirmation. astm e2109-01 pdf
