Description

ASTM D8394-21

Active Standard: Standard Test Method for Automated Measurement of Maturity, Fineness, Ribbon Width, and Micronaire of Cotton Fibers

ASTM D8394

Scope

1.1 This test method covers the determination of linear density (gravimetric fineness hereafter stated as fineness), maturity, micronaire, and ribbon width of cotton fibers from a loose, chemically untreated sample taken before harvest, during ginning, during mill processing or unraveled from raw (undyed) yarn or fabric.

1.2 This test method requires the use of an integrated instrument, for example, the Cottonscope (see Fig. 1), that measures the maturity, fineness, ribbon width, and micronaire of cotton fiber.2

FIG. 1 Cottonscope Instrument

Note 1: For another test method to determine the maturity of cotton fibers, refer to Test Method D1442.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.

1.5 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.
