Standard Test Method for Micronaire Reading of Cotton Fibers
 N D1448

Annotation

This test method covers the determination of the micronaire reading of loose cotton fibers by measuring the resistance of a specific mass (plug) of cotton fibers to air flow under prescribed conditions.

NOTE 1—For other methods for determining the fineness of fibers based on the air-flow principle, refer to Test Method D1449, Test Method for Specific Area and Immaturity Ratio of Cotton Fibers (Arealometer Method),2 and to Test Method D1282, Test Method for Resistance to Air Flow as an Indication of Average Fiber Diameter of Wool Top, Card Sliver, and Scoured Wool.

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 and health practices and determine the applicability of regulatory limitations prior to use.
