ASTM E345 – Tension Testing of Metallic Foil

← Back to all standards

ASTM E345 is the test method for tension testing of metallic foil at room temperature. Thin foil demands careful handling and gripping that a standard coupon test does not. To set up foil tensile testing, talk with our team.

What ASTM E345 Covers

The method applies to metallic foil, where specimen thinness makes alignment, gripping, and strain measurement the critical factors. It defines specimen form and the precautions needed to avoid tearing at the grips or premature failure.

Handling Thin Specimens

Foil is easily damaged and sensitive to grip pressure and misalignment. Low-mass grips, careful clamping, and precise alignment keep the failure in the gauge length. Non-contact or lightweight strain measurement avoids loading the specimen.

Properties Reported

Results include tensile strength and elongation, and, where the data support it, yield strength. These characterize foil for electronics, packaging, and battery applications.

Preparing Specimens

Clean edges free of burrs and nicks are essential, since any edge defect starts a tear. To configure a foil tensile setup with suitable grips, request a quote.

Reading the Designation

Cited with a year suffix such as ASTM E345-YY. Confirm the edition before finalizing fixturing.

Related Standards

ASTM E8/E8M is the general metals tensile method, and ISO 6892-1 covers room-temperature metal tensile testing.
