5.1 This test method is considered satisfactory for quality control testing and commercial shipment acceptance.5.1.1 In 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 test specimens that are from the lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using student's 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 found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.5.2 Finishes and changes in fabric surfaces may exert a large effect on pile retention of corduroy. Therefore, it may be desirable to test before as well as after laundering or drycleaning, or both.5.3 The separate testing of specimens on the face and back of the fabric is important in this test method since the pile pull-out may be due to abrasive action on either the face or back. With many pile fabrics, specifically corduroy constructions, pile retention properties are worse when abraded on the back.1.1 This test method covers the determination of the abrasion of pile fabrics when the loss of pile tuffs occur, sometimes called pile retention or pile pull out. It includes two procedures:1.1.1 Procedure A—The “Heavy Duty” procedure describes the test option for fabrics over 240 g/m2 (7 oz/yd2) or fabrics which should meet heavy duty end-use conditions of wear.1.1.2 Procedure B—The “Light Duty” procedure describes the test option for fabrics under 240 g/m2 (7 oz/yd2) or fabrics which should meet light duty end-use conditions of wear.1.2 The test method is intended for both regular, ribless woven corduroy or other woven pile fabric constructions.1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 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.

5.1 The depth of color achieved in dyeing fabric according to this practice is relative to the amount of sizing in the fabric. This practice employs a chromatic staining scale from 1 to 5 which is inversely proportional to the relative amount of sizing in the fabric. A light color stain indicates a low concentration of sizing and warrants a high numerical rating, while a dark color stain indicates a high concentration of sizing and warrants a low numerical rating.5.2 The accuracy of this practice depends upon the ability of the testing personnel to match the color of the stain to the colors in the AATCC 9 Step ChromaticTransference Scale.1.1 Using a color scale of 1 to 5, this practice describes the procedures for determining the presence and relative amount of sizing in fabrics made of undyed nylon or non-cationically dyeable polyester yarns prepared with a cationically dyeable sizing1.2 Procedures and apparatus other than those stated in this standard may be used by agreement of purchaser and supplier with the specific deviations from the standard acknowledged in the report.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 These test methods may be used for acceptance testing of commercial shipments; however, caution is advised because information about between interlaboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable.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 statistical bias between them using competent statistical assistance. As a minimum, use test samples for such comparative tests that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in the disparate results during initial testing, and that are randomly assigned in equal numbers to each laboratory for testing. The test results from the laboratories should be compared using statistical test for unpaired data at a probability level chosen prior to the testing series. If a 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.5.2 These test methods are useful to evaluate quality and cost control during the manufacture of pile yarn floor covering.5.3 The significance and uses of particular properties and test methods are discussed in the appropriate sections of the specified test methods.1.1 This guide covers the procedures listed as follows for testing woven, knitted and nonwoven backing fabrics designed for use in the manufacture of pile yarn floor coverings.
