ASTM F1306- Standard Test Method for Slow Rate Penetration Resistance of Flexible Barrier Films and Laminates

 

ASTM F1306 permits flexible barrier films and laminates to be characterized for slow rate penetration resistance to a driven probe.

The test is performed at room temperature, by applying a biaxial stress at a single test velocity on the material until perforation occurs.

The force, energy, and probe penetration to failure are determined.

ASTM F1306 / Significance and Use

Penetration resistance is an important end-use performance of thin flexible materials where a sharp-edged product can destroy the integrity of a barrier wrap.

This will permit package entry/exit of gases, odors, and unwanted contaminates, causing potential harm to the product and reducing shelf-life.

Material response to penetration will vary with numerous factors, such as film thickness, elastic modulus, rate of penetration, temperature, shape and type of probe.

Consequently, material responses from puncture to stretch may be observed and quantified using this method.

Although numerous combinations of experimental factors can be devised and used to simulate specific end-use applications, the recommended conditions in this

method should be followed for standard comparisons of materials.

ASTM F1306 / Apparatus

Universal Testing Apparatus, with a recording device.

Compression Load Cell(s).

Penetration Probe,   3.2 mm (0.125 in.) diameter hemispherical (biaxial stress) probe is recommended for general application and standard comparison of

materials and interlaboratory results.

Specimen Clamping Fixture,  An apparatus that holds the sample securely, preventing material slip so that testing is not affected.

Methods may include a pneumatic clamping mechanism or other mechanical means.

A sample test diameter of 35 mm (1.375 in.) is required for interlaboratory comparison of results.

(If other probes are used, a minimum clamp to probe diameter ratio of 10 to 1 is required.)

Specimen Cutter

*** Before conducting ASTM F1306 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
