The standard explicitly outlines two distinct approaches:

Under some conditions, a specific percentage of porosity is beneficial. It absorbs thermal shock in aerospace turbine blades.

When executing the steps outlined in the ASTM E2109-01 PDF, technicians must control several variables to prevent data skewing: This public link is valid for 7 days

Porosity is assessed by direct comparison of the specimen's microstructure against a set of standard referential images. Method B (Automated Image Analysis):

Uncontrolled banding and structural orientation cause several critical manufacturing challenges:

ASTM E2109 establishes the procedures for quantifying the porosity (voids) within a thermal sprayed coating. Thermal spray processes (like plasma spray, HVOF, or flame spray) naturally create coatings with some degree of porosity. Measuring this porosity is critical because it affects: Can’t copy the link right now

ASTM E2109-01 is officially titled Standard Test Methods for Determining Area Percentage Porosity in Thermal Sprayed Coatings (TSCs). The standard was first issued in 2001 by ASTM International and is maintained by Committee E04 on Metallography.
