This is the best place to get the current version (E2109-14 or newer) or the historical withdrawn version (E2109-01).
If you're looking for the ASTM E2109-01 PDF, you can purchase it from the ASTM website or other authorized distributors. It's essential to ensure that you're accessing the most up-to-date and accurate version of the standard.
Uncontrolled banding leads to distinct engineering vulnerabilities:
: Guidelines on how to document the average porosity, standard deviation, and the number of fields measured. Why It Was Withdrawn It is important to note that ASTM E2109-01 was officially withdrawn in 2010 astm e2109-01 pdf
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.
Are you troubleshooting a or setting up a new QC line?
Gear blanks and crankshafts require minimal banding to prevent distortion during heat treatment and carburizing. This is the best place to get the
Because variations in spray distances, gas expansion rates, and particle speeds shift these internal void structures, technicians rely on ASTM E2109-01 to consistently evaluate application performance. Scope and Core Prerequisites
For automated systems, spatial calibration (e.g., pixels per micrometer) must be verified using a certified stage micrometer. Step 4: Measurement and Data Reporting
Calibrate the optical microscope using a stage micrometer to ensure precise pixel-to-micrometer conversion. Are you troubleshooting a or setting up a new QC line
Follow a rigorous metallographic polishing sequence. The final surface must be scratch-free and represent the true internal structure of the coating. 4. Digital Image Analysis Procedure

Antimicrobial materials have become increasingly important in various industries, including:
ASTM E2109-01 is a critical technical standard used to determine the area percentage porosity
The inspector visually compares the prepared specimen against these reference images and selects the closest match. This is a practical, low-cost method suitable for routine quality checks and for facilities without access to automated image analysis equipment.
