Sales Know-How: What is Burst Strength?

At Acadian Industrial Textiles, our goal is to help you sell more products. And the most effective way to sell anything is to make sure that the products you recommend are appropriate for your customers’ needs.

In this blog series, we provide information about the technical specifications and testing criteria for our industrial textiles. The more you know about how these fabrics work and which applications they’re best suited for, the better you can sell them!

SO, WHAT IS BURST STRENGTH?

In burst strength testing, a force is applied to fabric to measure the conditions that will cause the textile to rupture. This test is designed for fabric that will bear weight or withstand force, such as:

LET’S GET TECHNICAL

There are different methods and machines used for measuring burst strength. Some common tests involve clamping fabric to an expandable diaphragm on a hydraulic testing machine. Other tests use a machine to calculate the amount pressure required to push a metal ball through the fabric.

In the industrial textile industry, the most common test standards are:

  • ASTM D 3786 – In this test, fabric is clamped tight across a hydraulic or pneumatic diaphragm. The diaphragm is then expanded until the fabric bursts.
  • ASTM D 6797 – This test uses a metal ball to test bursting strength. A fabric specimen is placed in a Constant Rate of Extension (CRE) Ball Burst machine. Then the machine pushes a metal ball against the fabric until it bursts.

HOW DO I KNOW IF MY FABRIC IS STRONG ENOUGH?

The most important thing to remember when selecting fabrics is that you compare “apples to apples.” If you’re trying to decide between two different fabrics, make sure you’re comparing consistent data. In other words, don’t compare two different materials that use different burst strength testing methods.
