Full Description

1.1This test method covers the classifying and counting of faults in spun yarns using capacitance testers.

1.1.1Protruding fibers or yarn hairiness, or both, are not determined as part of this method.

Note 1:For measuring protruding fibers or hairiness, or both, refer to Guide D5647.

1.2This test method provides for grading yarns by fault level and type.

1.3This test method is applicable to all single or plied spun yarns from natural or manufactured fibers or blends of each.

1.4The values stated in SI units are to be regarded as standard; the values in inch-pound units are provided as information only and are not exact equivalents.

1.5This 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.

1.6This 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.
