Standard Test Methods for Measurement of Physical Properties of Raw Cotton by Cotton Classification Instruments

SIGNIFICANCE AND USE
4.1 This test method is accepted for testing of bales of raw cotton in commercial shipments.  
4.2 This test method describes acceptable practices for testing of raw cotton using cotton classification instruments that are capable of testing the fiber properties of micronaire reading, length, uniformity index, strength, Rd (color), +b (color), percent area (trash) and particle count (trash).
SCOPE
1.1 This test method covers the measurement of color, trash content, micronaire, upper half mean length (length), uniformity index and breaking tenacity (strength) of raw cotton for cotton marketing using a cotton classification instrument.  
1.2 This test method is applicable to Upland and Extra Long Staple (ELS) raw cotton.  
1.3 This test method is applicable to roller and saw ginned raw cottons.  
1.4 This test method contains the following sections.
