ASTM D6797 – Standard Test Method for Bursting Strength of Fabrics Constant-Rate-of-Extension (CRE) Ball Burst Test

ASTM D6797 describes the measurement for bursting strength of woven and knitted textiles taken from rolls of fabric or fabric taken from garments.

NOTE 1—For the measurement of bursting strength with a hydraulic or pneumatic machine, refer to Test Method ASTM D3786.

For the measurement of the bursting strength by means of a ball burst mechanism, refer to Test Method ASTM D3787

NOTE 2—Constant Rate of Traverse (CRT) machines and Constant Rate of Extension (CRE) machines have been shown to provide different results.

When using a CRT device, refer to Test Method ASTM D3787.

Significance and Use

This method is used to determine the force required to rupture textile fabric by forcing a steel ball through the fabric with a constant-rate-of-extension tensile tester.

This is a new method and therefore the history of data is very small, however the agreement of within- laboratory data suggest this method may be considered

for acceptance testing of commercial shipments with caution.

Summary of Test Method

Set up the tensile tester for performing the ball burst test in accordance with the manufacture’s instructions.

A specimen of the fabric is securely clamped to the CRE machine without tension to the ball burst attachment.

A force is exerted against the specimen by a polished, hardened steel ball until rüptüre occurs.
