ASTM D3786: Burst Strength Testing for Paper and Fiberboard Materials

Durability in packaging is not an option, but a necessity; protecting delicate goods or withstanding pressures during storage and transport conditions must maintain the integrity of materials, which are made up of paper and fiberboard. A significant factor that ensures the durability of such material is burst strength: these materials can hold against the forces that make them tear or rupture without failing. Uncompromised quality achievement for manufacturers demands adherence to standards for such a requirement as burst strength.

This is where ASTM D3786, the globally recognized test standard, comes in. This standard offers a well-defined guideline for the testing of burst strength of materials such as paper, fiberboard, and even textiles. Let's dig deeper into its applicability and how advanced testing equipment, such as Testronix's Bursting Strength Tester, makes compliance easy and ensures the best performance from the material.

What is ASTM D3786?

ASTM D3786 is the standard test method for deciding the bursting strength of different materials, paper, and fibreboards utilizing a diaphragm pressure analyzer. This standard gauges how much strain it takes for a material to burst.

This test is particularly vital in industries where materials undergo great stress, such as corrugated box production, nonwoven fabrics, or heavy-duty packaging. The material must pass certain thresholds of durability in ASTM D3786 so that no failure occurs in the application of the product.

How Bursting Strength Testing Works?

The diaphragm of the bursting strength tester is central in this test. It employs a rubber diaphragm, to which pressure is uniformly applied to the material that is under test. The pressure keeps on increasing steadily to rupture the material. Pressure at rupture represents the point of the material's strength.

Test Procedure

• Sample Preparation: Put the material within the clamping ring securely to avoid wrinkles and folds.

• Testing Conditions: Uniformly applied pressure under controlled conditions to ensure accuracy.
• Pressure Application: Gradually increase pressure through a hydraulic system until the material bursts.

• Recording Metrics: The highest force or pressure applied at the time of rupture

This process ensures accurate measurement while following the guidelines set by ASTM D3786.

Measuring Parameters

Bursting Pressure (kg/cm² or psi): The pressure at the point of failure.

Material Performance: The obtained pressure signifies the material's strength and robustness.
