Laminated Glass Interlayer Inspection

Inspection template for laminated glass quality checks focused on interlayer bubbles, delamination, contamination, and edge quality per ASTM C1172. Used by safety glazing producers to verify lamination quality before release.

Inspection Details

• Panel identification recorded
  Record panel ID, batch/lot number, size, and production date.
• Inspection stage confirmed
  Select the point in the process where the inspection was performed.
• Reference standard verified
  Confirm the inspection is being performed against ASTM C1172 and the applicable internal acceptance criteria.
• Inspector and date recorded
  Capture the inspection timestamp.
• Product type confirmed as laminated glass
  Verify the item under inspection is laminated glass and not monolithic glass or another glazing product.

Surface and Interlayer Defects

• Interlayer bubbles present within acceptable limit
  Inspect both faces under normal and oblique lighting for visible bubbles, blisters, or trapped air in the interlayer.
• Delamination observed at any location
  Check for separation between glass and interlayer, especially near edges, corners, and stress points.
• Interlayer contamination visible
  Inspect for dust, foreign particles, haze, streaks, or embedded contamination within the laminate.
• Surface scratches, chips, or optical defects within tolerance
  Check for scratches, chips, distortion, or other visible defects that may affect safety or appearance.

Edge Quality and Seal Integrity

• Edge quality meets acceptance criteria
  Inspect exposed and concealed edges for chips, cracks, uneven trimming, and edge damage.
• Edge seal is continuous and intact
  Verify the edge seal shows no breaks, voids, lifting, or visible pathways for moisture ingress.
• Edge moisture, clouding, or discoloration present
  Check for signs of moisture ingress, fogging, clouding, or discoloration at the laminate edge.
• Edge finish uniform across panel
  Rate the overall consistency of edge finish and workmanship.

Documentation and Disposition

• Non-conformances documented
  Select all defect categories observed during inspection.
• Corrective action assigned
  Document rework, hold, scrap, or escalation actions taken for any failed item.
• Disposition selected
  Choose the final disposition for the inspected panel.
• Photo evidence attached for defects
  Attach photos showing any observed defects, especially bubbles, delamination, contamination, or edge damage.
