ASTM F1886 Standard Test Method for Determining Integrity of Seals for Flexible Packaging by Visual Inspection
Visual inspection requires a trained technician to perform 100-percent inspections on a sterile package. It is typically performed during sealer validation, transit or shelf-life studies. Visual inspection evaluates potential risks for long-term sterility of the packaging system. Although the standard refers solely to seal integrity, industry commonly performs whole-package visual inspection. This test seeks to identify any abnormalities such as seal defects, pinholes, abrasion or other risks.
