ASTM D6611-23

Standard Test Method for Wet and Dry Yarn-on-Yarn Abrasion Resistance

SIGNIFICANCE AND USE
5.1 This test method is intended for testing dry and wet abrasion resistance of manufactured fiber yarns. This test method is useful for ropes intended for use in the marine environment and for knitted hoses for various applications. The test method has been used with yarns having linear densities ranging from 65 tex to 335 tex, but may be used with yarns outside these ranges.  
5.2 Yarn to yarn friction is known to have a significant influence on abrasion resistance. To determine the coefficient of friction, use Test Method D3412.  
5.3 Limited interlaboratory correlation testing has been conducted to date. Single-laboratory testing, in accordance with ASTM practices, has been conducted. Test results should be used with caution.  
5.4 This test method is intended to provide additional data for specific applications such as mentioned in 5.1 and is not intended for quality control or test reports.  
5.5 If there are differences of practical significance between reported test results for two or more laboratories, comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum the test samples used should be as homogeneous as possible, be drawn from the material from which the disparate test results were obtained and be randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two or more laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to testing. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.  
5.6 This test method is conducted at one or several applied tensions that may depend upon the yarn material and size. The number and magnitudes of applied tensions and the number of eight specimen sets generally are agreed up...
SCOPE
1.1 This test method describes the measurement of abrasion resistance properties for manufactured fiber yarns in dry and wet conditions.  
1.2 This test method applies to manufactured yarns used in rope and knitted hose making.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are provided for information only.  
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.

4. Summary of Test Method
4.1 A length of yarn is interwrapped in contact with itself between three pulleys that are positioned in a defined geometry to
produce a specific intersection angle. A weight is attached to one end of the yarn to apply a prescribed tension. The other end is
drawn back and forth through a defined stroke at a defined speed until the yarn fails due to abrasion upon itself within the
interwrapped region. The yarn abrasion test can be conducted in either the dry state or the wet state.
