Standard Test Methods for Determining Area Percentage Porosity in Thermal Sprayed Coatings

When you’re working with thermal sprayed coatings, one of the most critical quality checks is measuring porosity—those tiny voids that can affect how well a coating performs. ASTM E2109-01 provides standardized methods to determine the area percentage porosity in these coatings, giving you reliable, repeatable results whether you're doing manual comparisons or using automated image analysis.

Even if you plan to use automated analysis, having your team practice with the seven standard images builds essential pattern recognition skills. I can provide targeted tips to optimize your

because it contains the specific technical parameters required for audit-ready reporting. While the standard was originally published in 2001, it remains a foundational document for laboratories implementing automated image analysis systems. Current Status It is important to note that ASTM E2109-01 was withdrawn in 2023

Run the analysis across multiple randomly selected fields to ensure a representative sample. The final report should include the mean area fraction, standard deviation, and the confidence interval. Accessing the PDF Legally

Method B uses computerized image analysis equipment to automatically calculate the area percentage porosity. This approach offers greater precision, repeatability, and eliminates human subjectivity. It's particularly valuable when you need statistically robust data or when evaluating coatings for critical applications. ASTM standards undergo systematic reviews every few years

The "-01" suffix indicates the standard was originally approved or significantly revised in 2001. Though it has undergone reapprovals to maintain its active status, the fundamental technical methodologies remain the industry benchmark for automated rating systems. Why Microstructural Banding Matters

Modern systems use automated thresholding algorithms, but manual verification is still required under the standard to prevent artifacts from being counted. 4. Image Processing and Measurement

Spills of chemical dyes, acids, and bases are common. While E2109-01 focuses on staining rather than chemical etching , it is a first-line test for lab floor coatings.
