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

 

ASTM F1306 is a standard test method used to evaluate the slow rate penetration resistance of flexible barrier films and laminates. This test measures the ability of materials such as plastic films, paper, and composite laminates to resist penetration under a slow, controlled force. The test is vital for understanding the performance of flexible barrier materials in applications such as packaging, where materials are exposed to punctures, abrasions, or impacts during use.

This test method is used to simulate real-world conditions in which films and laminates must withstand slow, consistent forces that could cause damage, punctures, or leaks, thereby testing their overall strength and durability in critical applications like food packaging, medical supplies, and industrial materials.

What Does ASTM F1306 Measure?

ASTM F1306 is designed to measure the penetration resistance of flexible films and laminates when subjected to slow rate forces. Specifically, the test evaluates the force required to penetrate the material using a rigid puncture probe under a constant and slow rate of application.

Key aspects measured include:

• Penetration resistance: The force required for a rigid probe to puncture the material.

• Material integrity: How well the material maintains its structure under slow, steady pressure.

These results help determine the strength and durability of barrier materials in packaging applications where penetration resistance is crucial, such as preventing leaks, tears, or breaches in containers that store sensitive products.

Test Specimen

Specimen Dimensions

• Shape: Rectangular or circular specimens, depending on the material size.

• Thickness: The material’s thickness is measured prior to testing, typically using a micrometer, as the resistance can vary with thickness.

• Size: Typically 50 mm x 50 mm squares for film testing, but sizes may vary depending on the material or testing machine requirements.

Test Equipment and Fixture

Test Setup

The test requires a specialized slow-rate penetration tester, which includes the following components:

• Puncture probe: A rigid, conical or needle-shaped probe that is used to penetrate the specimen material.

• Loading system: A system to apply a consistent and controlled force at a slow rate, often in the range of 2-5 mm/min. A Universal Testing Machine is commonly used for this type of puncture testing. 

• Fixture: The specimen is placed between two supports to prevent slippage during the test, while ensuring that only the probe applies force to the material.

The test applies pressure at a constant rate, and the penetration is measured as the distance the probe travels until the material breaks or punctures. This simulates the impact that can occur in packaging when films or laminates encounter slow, sustained forces, like those from mechanical equipment or product handling.

Test Procedure

1. Specimen Preparation: Cut the specimen into the required size (e.g., 50 mm x 50 mm squares) and measure its thickness. Ensure the specimen is free from wrinkles, air bubbles, or imperfections that could affect the results.

2. Mounting the Specimen: Place the specimen between the fixture supports, ensuring it is held taut and securely in place.

3. Puncture Test: Begin the test by applying force using the rigid probe at a slow, controlled rate. The probe should penetrate the material until it either punctures or breaks the specimen.

4. Data Collection: Record the force required to penetrate the material and the distance traveled by the probe. These values are used to determine the material’s penetration resistance.

Results Interpretation

• Penetration Resistance is expressed in terms of the force (measured in Newtons or pounds) that was required to puncture the material.

• The distance traveled by the probe can also be recorded, providing additional insights into the material’s behavior under sustained stress.

High penetration resistance indicates that the material is more resistant to poking, tearing, or puncturing, which is essential for barrier films used in demanding environments such as food packaging, medical packaging, and industrial protective materials.

Applications

ASTM F1306 is commonly used in the following industries:

• Food Packaging: Testing barrier films and laminates to ensure food safety by preventing punctures and leaks.

• Medical Packaging: Ensuring that medical device packaging remains intact under normal handling conditions, protecting sensitive items.

• Industrial Applications: For testing materials used in protective coverings or wrapping films, such as those for electronics or machinery.

• Consumer Products: Evaluating packaging for consumer goods that need to withstand mechanical stress during shipping and storage.
