Historical Version s - view previous versions of standard. More D Test Method D is considered satisfactory for acceptance testing of commercial shipments of textiles fabrics for bursting strength since the method has been used extensively in the trade for acceptance testing. In cases of disagreement arising from differences in values reported by the purchaser and the seller when using Test Method D for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller should be determined with comparison based on testing specimens randomly drawn from one sample of material of the type being evaluated. The test samples used should be as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to the laboratories for testing.

In cases of disagreement arising from differences in values reported by the purchaser and the seller when using Test Method D for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller should be determined with comparison based on testing specimens randomly drawn from one sample of material of the type being evaluated.

The test samples used should be as homogeneous as possible, drawn from the material from which the disparate test results were obtained, and randomly assigned in equal numbers to the laboratories for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data at a probability level chosen prior to the testing series.

If a bias is found, either the cause must be determined and corrected or future test results must be adjusted in consideration of known bias. Within the test, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system may be used independently of the other. Combining values from the two systems may result in nonconformance within the specification. This standard does not purport to address all of the safety concerns, if any, associated with its use.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D3787

ASTM D is used to determine the resistance of textiles to physical stresses. Using the ball shape, the strain is spread out over a relatively large area so there are no localized points of stress such as in other types of puncture tests that may use a sharp point. The diameter of the ball is 1 inch and the diameter of the inner circle is 1. See the literature for more information. The D puncture fixture is specifically design to conform to this standard.
