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.
