If you are looking to understand or summarize the contents of this document, it typically includes:

: It provides the methods for measurement but does not define what levels of porosity are "acceptable"; those limits are typically set by specific project requirements or industry contracts. Key Test Methods Defined

Compliance with this standard is frequently mandated in high-stakes supply chains where structural failure is not an option: astm e2109-01 pdf

Thermal sprayed coatings (TSCs) are vital across numerous industries, providing corrosion resistance, wear resistance, and thermal insulation. However, the performance of these coatings is directly linked to their microstructural integrity, particularly the presence of pores formed during the spraying process. The provides definitive test methods for quantifying this porosity.

Thermal sprayed coatings (TSCs) are applied in industries ranging from aerospace to power generation, often to provide wear resistance, corrosion protection, or thermal barrier properties. But here's the challenge: during the spraying process, porosity can form due to either a lack of fusion between sprayed particles or the expansion of gases trapped during coating application. If you are looking to understand or summarize

If you are performing a test that specifically requires (e.g., due to a customer specification), I recommend:

Understanding ASTM E2109-01: The Standard for Quantifying Area Percentage Porosity The provides definitive test methods for quantifying this

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