To perform tests according to the 2001 standard, a laboratory must have:
E2109 is more rigorous for and non-foam PSAs where creep behavior is critical.
To achieve reproducible results that comply with the standard, laboratories must follow a strict workflow: Step 1: Metallographic Sample Preparation
In gas turbine engines, thermal barrier coatings (TBCs) require a precise level of controlled porosity to provide optimal thermal insulation and strain tolerance.
The standard also mandates that the user be able to distinguish between true porosity and other features such as oxides, embedded grit from surface preparation, or pullouts caused by improper polishing. If there are doubts about specimen preparation, the standard suggests using confirmatory techniques like energy dispersive spectroscopy (EDS) or scanning electron microscopy (SEM).
The ICS Code for this standard is , and the standard contains 8 pages.

ASTM E2109-01 provides a rigorous, foundational methodology for quantifying microstructural phases via manual point counting, serving as a reliable alternative to automated image analysis. It is highly valued for its accuracy in calibrating digital systems and for providing cost-effective, high-quality data in labs lacking specialized software.
The standard specifically focuses on using computerized image analysis systems. These systems evaluate digital images captured from optical microscopes or scanning electron microscopes (SEM). By automating the evaluation, the standard eliminates the human bias and variability often found in manual point-counting methods. Key Details of the Standard:
