Description

ASTM D2130-22

Active Standard: Standard Test Method for Diameter of Wool and Other Animal Fibers by Microprojection

ASTM D2130

Scope

1.1 This test method covers a procedure, using the microprojector, for the determination of the average fiber diameter and the fiber diameter variation on wool and other animal fibers, such as mohair, cashmere, alpaca, camel’s hair, etc. (Note 1) in their various forms.

1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

Note 1: This test method may also be applied to any fibers having a round cross section and accordingly may be used many times for melt-spun man-made fibers such as polyamides, polyesters, and glass; also it may be applied to a limited number of polyacrylics and regenerated cellulose type fibers. The values given in Appendix X1 for density and correction factors, however, apply only to wool and should not be used for other fibers. For suitable values for the density of other fibers, see Table 5 in Test Methods D629, Quantitative Analysis of Textiles.

Note 2: In subsequent sections of this test method, the term “wool” also signifies mohair or other fibers if the circumstances are applicable.

Note 3: For fineness specifications for wool, wool top, mohair, mohair top, alpaca, and cashmere, refer to Specifications D3991 and D3992, Specification D2252, Test Method D2816.

1.3 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.

1.4 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.
