The ASTM E2109-01 standard provides established test methods for determining the area fraction and pore size distribution of thermal spray coatings using digital image analysis.

Feature Recognition: The software must be able to distinguish between actual pores and other features like oxides or secondary phases.

  • ASTM Compass (The full digital library).
  • ScienceDirect or Engineering Village.

3. Test Setup (Schematic Summary)

  • Test panel: Typically 50 mm × 125 mm stainless steel (type 302/304, mirror finish, Ra = 50 ± 25 nm).
  • Specimen size: 25 mm × 25 mm adhesive-coated article.
  • Bond area: Exactly 25 mm × 25 mm (625 mm²), using a 2 kg rubber roller (5 passes) or specified lamination pressure.
  • Load: Usually 500 g, 1000 g, or 2000 g, depending on adhesive strength.
  • Dwell time: 15–30 minutes before loading (to allow adhesive flow).
  • Angle: Load applied parallel to bond line (±2°).
  • Temperature: Controlled chamber (±1°C).
  • Failure detection: Automatic timer stops when bond separates completely or when creep exceeds a defined threshold (e.g., 5 mm movement).

Important Note: If you need the most current version for a strict regulatory compliance (e.g., ISO 17025 accreditation), you should purchase the latest reaffirmed edition. If you need the original methodology for historical research or legacy product testing, the 2001 PDF is what you require.
