Significance and Use
This test method is used for acceptance testing of commercial shipments. Comparative tests as directed in 5.2 may be advisable.
In a case of a dispute arising from differences in reported test results when using this test method, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test samples that are as homogenous as possible and are from a lot of material of the type in question. The test samples then should be assigned randomly in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using a statistical test for unpaired data and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results with consideration to the known bias.
This test method is useful to evaluate quality and cost control during the manufacture of pile yarn floor covering. Both appearance and performance of the pile floor covering can be affected by delamination of the secondary backing.
1.1 This test method covers the measurement of the resistance to delamination of the secondary backing applied to some pile yarn floor coverings.
1.2 This test method is applicable to all backings including natural manufactured fibers or attached cushion.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
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.
