ASTM F2391

ASTM F2391 is a technical standard that describes a test method for measuring package and seal integrity using helium as the tracer gas. It provides a structured way to evaluate whether a package or sealed system can maintain its barrier performance under test conditions. For manufacturers and quality teams, this matters because reliable seal integrity testing can help support product protection, leak detection, and consistent compliance-focused evaluation.

What is ASTM F2391?

ASTM F2391 is an ASTM standard test method centered on helium tracer gas measurement for package and seal integrity. In practical terms, it outlines a way to assess whether a package closure or seal is performing as intended by using helium as a detectable tracer. The standard is generally used as a technical reference for controlled integrity testing, helping users apply a repeatable method when evaluating packaging performance, seal quality, and potential leakage concerns.

Where is ASTM F2391 used?

This standard is commonly used in packaging test environments where seal integrity needs to be verified with a sensitive measurement method. It may be applied in laboratory or quality control workflows that assess sealed packages, containers, or other packaging systems designed to protect contents from leakage or contamination. ASTM F2391 is especially relevant when a helium-based test approach is preferred for detecting small integrity issues and supporting objective product evaluation.

Why is ASTM F2391 important?

ASTM F2391 is important because it gives organizations a recognized method for evaluating package and seal integrity in a consistent way. That consistency can support compliance efforts, procurement decisions, and internal quality control programs. Using a defined test method also helps reduce uncertainty when comparing packaging designs or seal performance across batches. For teams focused on product reliability, it provides a practical basis for testing, documentation, and risk reduction.
