The FDA explicitly states this standard is relevant . It also cross-references this method with critical international standards like ISO 11607-1 and ISO 11607-2 , which are essential for packaging terminally sterilized medical devices. This recognition solidifies the vacuum bubble test as a cornerstone in the validation of sterile barrier systems globally. astm d3078 pdf 2021
An important procedural note: both the test sample and the test fluid must be at equilibrium with normal room temperature to ensure consistent results.
A clear, rigid container (usually acrylic) that can withstand a vacuum.
This test method is applicable to flexible packaging materials, including pouches, bags, and sachets. Common industries relying on this standard include: Sterile blister packs and pouches. ASTM D3078 is titled: "Standard Test Method for
