(Test Method)Standard Test Method for Bursting Strength of Textile Fabrics—Diaphragm Bursting Strength Tester Method
Standard Test Method for Bursting Strength of Textile Fabrics<span class='unicode'>—</span>Diaphragm Bursting Strength Tester Method
SIGNIFICANCE AND USE
This method for the determination of diaphragm bursting strength of knitted, nonwoven and woven fabrics is being used by the textile industry for the evaluation of a wide variety of end uses.
In cases where test results obtained using the procedures in Test Method D 3786 have not been correlated with actual performance, Test Method D 3786 is considered satisfactory for acceptance testing of commercial shipments of textile fabrics for bursting strength since the method has been used extensively in the trade for acceptance testing. In cases where disagreement arising from differences in values reported by the purchaser and the supplier when using Test Method D 3786 for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the supplier should be determined with comparison based on testing specimens randomly drawn from one sample of material of the type being evaluated.
Note 2—The kind of load transfer and stretch that occur when knitted goods and nonwoven fabrics are worn are prevented by clamping them as described in this method.
SCOPE
1.1 This test method describes the measurement of the resistance of textile fabrics to bursting using a hydraulic or pneumatic diaphragm bursting tester. This test method is generally applicable to a wide variety of textile products.
1.2 This test method may also be applicable for stretch woven and woven industrial fabrics such as inflatable restraints.
1.3 The values stated in SI units are to be regarded as standard.
Note 1—For the measurement of the bursting strength by means of a ball burst mechanism, refer to Test Method D 3787.
1.4 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.
