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.

Industry Application

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, the industry commonly performs the whole-package visual inspection. This test seeks to identify any abnormalities such as seal defects, pinholes, abrasion, or other risks.

Frequently Asked Questions

What is Visual Inspection Testing per ASTM F1886?
A1: Visual inspection covers the determination of channels in the package seal down to a width of 0.003 inches with a 60 – 100% probability. This test method is applicable to packages with at least one transparent side so that the seal area may be clearly viewed.

What is the purpose of visual inspection test?
This test method provides a qualitative visual inspection method to evaluate the appearance characteristics of unopened, intact seals to determine the presence of defects that may affect the integrity of the package.
