These test methods cover the color, trash content, micronaire, length, length uniformity, strength and elongation of cotton fibers using the Spinlab System HVI 900 SA or the Motion Control, Inc. Systems HVI 3500 and HVI 4000 that are a series of instruments connected to single dedicated programmed computers.

Formerly under the jurisdiction of Committee D13 on Textiles, these test methods were withdrawn in June 2004 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.

1.1 These test methods cover the color, trash content, micronaire, length, length uniformity, strength and elongation of cotton fibers using the Spinlab System HVI 900 SA or the Motion Control, Inc. Systems HVI 3500 and HVI 4000 that are a series of instruments connected to single dedicated programmed computers.

1.2 These test methods are applicable to loose fibers taken from raw or partially processed cotton and some types of cotton waste.

1.3 These test methods contain the following sections:
Color of Cotton (Section 7 to 15)
Trash Content of Samples of Cotton Fibers (Section 16 to 24)
Micronaire Reading of Cotton Fibers (Section 25 to 33)
Length and Length Uniformity of Cotton Fibers (Section 34 to 42)
Breaking Tenacity and Elongation of Cotton Fibers (Section 43 to 51)
Precision and Bias (Section 52)

1.4 The values stated in inch-pound and SI units are to be regarded separately as the standard. The values given in parentheses are for information only.

1.5 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.
