Standard Test Method for Bursting Strength of Textiles-Constant-Rate-of-Traverse (CRT) Ball Burst Test

ASTM D3787 serves as a fundamental tool for assessing the resistance of textiles to physical stresses. Employing a ball-shaped apparatus, this method ensures the even distribution of strain across a substantial surface area, thereby mitigating the presence of localized stress points commonly observed in alternative puncture tests utilizing sharp points.

This test uses the same exact fixture as the ASTM D6797 test. 


The test apparatus features a ball with a 1-inch diameter, and an inner circle with a diameter of 1.75 inches (approximately 44.45mm). Square samples measuring 2 inches on each side are affixed securely using screws on the fixture's ring. A standard size adapter of 5/8" is employed, and additional details can be found in the accompanying literature.


The D3787 puncture fixture is specifically design to The puncture fixture designed for ASTM D3787 adheres meticulously to the prescribed standards. Notably, the fixture incorporates a specialized ridge pattern between the two circular plates where the textile sample is positioned. These ridges or channels play a crucial role in securing the sample and preventing any undesired slippage during testing.


Calculation parameters encompass the burst strength, defined as the peak load just prior to rupture. Analyses extend to the determination of average burst strength, focusing on the variability observed among different textile samples and across various tests. The Galdabini Graphwork 6 software is adept at conducting individual test analyses and statistical assessments for batches of tests. Furthermore, the system facilitates the generation of detailed test reports suitable for distribution to clients.
