TAPPI T403 Burst Strength of Paper

Testing Standard:

TAPPI T403 Bursting Strength of Paper ie. TAPPI T403 Burst Strength of Paper

Standard Number
TAPPI T403

Standard Title
Bursting Strength of Paper, Test Method

Overview for TAPPI T403 Burst Strength of Paper:

TAPPI T403 Burst Strength of Paper details the method of obtaining the maximum bursting strength measurement of paper and other flat paper products having a burst strength range of 7-175 psi (50-1200 kPa) and a thickness of up to 0.025” (0.6mm).

This test measures the ability of paper to resist rupturing when subjected to pressure, such as when a package is being compressed during shipping or handling.

The test involves clamping a sample of paper between two flat plates and applying pressure until the paper ruptures. The maximum pressure required to cause the paper to burst is recorded as the burst strength, which is typically measured in pounds per square inch (psi).

Burst strength is an important property of paper, especially in packaging applications where the paper needs to withstand the stresses of shipping and handling. It can also be an indicator of paper quality, as stronger papers tend to be more durable and have a higher resistance to tearing and other forms of damage.

Purple Diamond Testing offers TAPPI T403 Bursting Strength of Paper as part of our packaging compliance and validation services.

Rationale for TAPPI T403 Burst Strength of Paper:

TAPPI T403 – Bursting Strength of Paper. Can be used to evaluate the strength of many paper materials that fall within the above parameters. Inexpensive and relatively easy to perform, results simulate the strength characteristics of some end use requirements. This is achieved by securing the material between annular clamps and applying increasing pressure through a rubber diaphragm until failure occurs. The maximum pressure up to the material rupture is recorded as the bursting strength.
