Standard Test Method for Grading Spun Yarns for Appearance
1.1 This test method covers the grading of singles spun yarns for appearance.
1.2 This test method does not apply to plied yarns.
1.3 The values stated in either inch-pound or SI units are to be regarded separately as the standard. The values stated in each system are not exact equivalents, therefore, each system must be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 This standard does not purport to address the safety concerns 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. 2
