Significance and Use:

Refer to the particular test method cited for the property of interest for specific significance and use statements.

In case of a dispute arising from the differences in reported test values when using the test methods listed in these test methods for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine whether a statistical bias exists between their laboratories. Competent statistical assistance is recommended for the investigation of this bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens should then be assigned randomly, in equal numbers, to each laboratory for testing. The average results from the two laboratories should be compared using Student’ t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be determined and corrected or the purchaser and supplier must agree to interpret future results in the light of the known bias.

Scope:

1.1 This guide covers procedures for testing nonwoven fabrics. The test procedures appear in the following sections:

Absorbency21
Air Permeability8
Breaking Force and Elongation9
Bursting Strength10
Conditioning7
Dimensional Change20

Resin Binder Distribution22
Seam Breaking Strength13
Trapezoid Tear14
Tongue Tear (Single Rip)15
Elmendorf Tear16
Thickness19

Note 2—The terms "machine" and "cross machine" must be substituted for "warp" and "filling," respectively, throughout these test methods wherever pertinent.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only and may be approximate.

1.3 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.
