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

The ASTM D6797 test defines the burst strength measurement of woven and knitted textiles from fabric rolls or fabrics from garments.

For measurement of burst strength with a hydraulic or pneumatic machine, refer to Test Method D3786. For measurement of burst force through a ball burst mechanism, refer to Test Method D3787.

Constant Motion Rate (CRT) machines and Constant Extension Rate (CRE) machines have been shown to give different results. Refer to Test Method D3787 when using a CRT device.

Values ​​specified in SI units or US conventional units should be considered standard, but should be used independently of each other. US conventional units can be approx.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.

Fabric samples should be cut from a bolt or roll. Samples should be used from the middle of the bolt of the fabric. Each square specimen measures 5x5 inches.

The ball on the fixture is 1 inch in diameter and spherical. The inner diameter of the lower anchor hole should be 1,75 inches in diameter. Fixture plates have special grooves that help hold the sample.

Bursting strength is given by the maximum peak load seen during testing. For a positive test result, the sample must be ruptured. Many quality control departments will take a sample lot of 5 and average the results.
