Substrate Surface Energy Dyne Test Log - ASTM D2578

Inspection log for recording dyne pen or test-fluid surface energy readings across a substrate web before coating, printing, or laminating, and verifying the treated surface meets the minimum dyne value for adhesion readiness.

Inspection Details

• Inspection date and time
• Inspector name
• Production order, lot, or roll ID
• Process stage
• Required minimum dyne level
• Reference document or SOP
  Enter the applicable work instruction, customer specification, or internal SOP used for the test.
• Inspection notes

Substrate and Surface Identification

• Substrate material
• Surface side tested
• Surface is clean, dry, and free of visible contamination
  Check for dust, oil, release agents, moisture, fingerprints, or other contamination that could affect the reading.
• Surface treatment method
• Visible surface defects that may affect adhesion

Test Method and Conditions

• Test method
  Record whether a dyne pen or test fluid was used in accordance with ASTM D2578 or site procedure.
• Test fluid or pen series
  Record the manufacturer, series, or nominal dyne value of the pen/fluid used.
• Ambient temperature
• Relative humidity
• Test area prepared and free of surface contamination

Dyne Readings Across the Web

• Left edge dyne reading
  Record the measured surface energy at the left edge or designated edge position.
• Left-center dyne reading
• Center dyne reading
• Right-center dyne reading
• Right edge dyne reading
• Lowest reading meets minimum required dyne level
  The lowest reading across the web must meet or exceed the required minimum dyne level.

Deficiencies and Corrective Action

• Non-conformance identified
  Mark yes if any reading is below the minimum dyne requirement or if contamination/condition prevents a valid result.
• Deficiency description
  Describe the deficiency, including affected web position(s), measured values, and observed condition.
• Corrective action taken
  Record actions such as re-cleaning, re-treating, adjusting treatment settings, segregating material, or retesting.
• Retest required
  Indicate whether the substrate must be retested before release.
