(Test Method)Standard Test Method for Tuft Height of Pile Floor Coverings
Standard Test Method for Tuft Height of Pile Floor Coverings
SIGNIFICANCE AND USE
5.1 This test method is useful in quality and cost control during the manufacture of pile yarn floor covering. Both appearance and performance can be affected by changes in the tuft height.
5.1.1 In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, 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 specimens that are as homogeneous as possible and are from a 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 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 view of the known bias.
SCOPE
1.1 This test method covers the determination of tuft height using a grooved specimen holder. It applies to cut-pile and loop-pile floor covering after adhesive backing has been applied to bond the pile yarn to the backing fabric.
1.2 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.
1.3 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.
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.

4. Summary of Test Method
4.1 For cut pile floor covering, individual tuft leg specimens of like character (either cut or loop and of uniform height) are cut
as closely as possible to the surface of the backing of a pile floor covering sample and placed, one at a time, in a grooved specimen
holder that maintains the tuft yarn in a straight line while the length of the tuft leg is measured using a graduated scale and a
magnifying glass.
4.2 For loop pile floor covering, the two tuft legs forming the loop are each severed from the adjacent binding sites at the
backing surface to provide a specimen of twice the tuft height and the length measured as in 4.1.
5. Significance and Use
5.1 This test method is useful in quality and cost control during the manufacture of pile yarn floor covering. Both appearance
and performance can be affected by changes in the tuft height.
