scope:

1.1 These test methods cover the measurement of mass per unit length (linear density) of textile fibers and filaments. Direct weighing and vibroscope procedures with modifications for crimped and uncrimped fibers are included. The options and sections are listed below.

  Option Sections
 
  A-Fiber Bundle Weighing  7 - 15
  B-Single-Fiber Weighing 16 - 23
  C-Vibroscope, General 24 - 30
    35 and 36
  C1-Uncrimped Fibers 31 and 32
  C2-Crimped Fibers 33 and 34
  Precision and Bias 37 and 38

Note 1: For linear density of short lengths of yarn, refer to Test Method D1059. For cotton linear density, refer to Test Methods D1769 and D2480. For measurement of wool diameter, refer to Test Methods D1282, D2130, and D3510.

1.2 The crimp, taper, and cross-sectional shape of the fiber may influence the linear density measured by single-fiber weighing and vibroscope.

1.3 These test methods measure the linear density of fibers with moisture in equilibrium with the standard atmosphere for testing textiles. The fiber moisture under these conditions is not necessarily the same as the commercial moisture regain for the fibers.

1.4 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 exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.

1.5 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.

1.6 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.
