(Test Method)Standard Test Method for Bond Strength of Bonded, Fused, and Laminated Apparel Fabrics
Standard Test Method for Bond Strength of Bonded, Fused, and Laminated Apparel Fabrics
SIGNIFICANCE AND USE
5.1 This test method for the determination of bond strength of bonded, fused, or laminated apparel fabrics, is considered satisfactory for acceptance testing of commercial shipments of bonded and laminated apparel fabrics.
5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative test that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing. Randomly assign specimens in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data and a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.
SCOPE
1.1 This test method covers procedures for characterizing the bond strength of bonded, fused, and laminated apparel fabrics before or after drycleaning and laundering.
1.2 The values stated in SI units are to be regarded as standard; the values in parentheses are provided as information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. See 6.1.1 for a specific warning.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.2 For definitions of other textile terms used in this test method, refer to Terminology D123.
4. Summary of Test Methods
4.1 Bench marks are placed at specified distances on the fabrics, which are then measured, and subsequently dry-cleaned, or
laundered and dried, or both, through a prescribed cycle that is repeated a specified number of times. The drycleaned or washed
specimens are examined for appearance and delamination and measured to determine any accompanying shrinkage and, if desired,
tested to determine the strength of the bond.
5. Significance and Use
5.1 These test methods for the determination of properties of bonded, fused, or laminated apparel fabrics, are considered
satisfactory for acceptance testing of commercial shipments of bonded and laminated apparel fabrics since the methods have been
used extensively in the trade for acceptance testing.
