Standard Test Methods for Linear Density of Textile Fibers
Available format(s)

Hardcopy , PDF

Language(s)

English

Published date

24-07-2018

1.1These 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.

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

1.3These 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.

1.4The 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.

1.5This 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, health, and environmental 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.
