Visual Inspection Test
ASTM F1886 Standard Test Method for Determining Integrity of Seals for Flexible Packaging by Visual Inspection This ASTM visual inspection method is a non-destructive test used for flexible and rigid packages with a minimum of one transparent side so that the seal is in plain view. Though it is non-destructive, the ASTM F1886 procedure is limited compared to some other methods in terms of the defects it can detect. The effectiveness also depends on factors such as the size of the channel, the materials used in the packaging, whether or not magnification is used, type of adhesion used, and the visible contrast between sealed and unsealed areas.
The ASTM standard for 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.
