1.1 This test method covers the determination of the percentage of mature fibers in a sample of loose, chemically untreated cotton fibers, whether taken before processing or unravelled from a textile product.
1.2 This test method gives two optional procedures for determining maturity, as follows:
1.2.1 Procedure 1—Sodium Hydroxide Swelling.
1.2.2 Procedure 2—Polarized Light.
Note 1—For other test methods for the determination of maturity of cotton fibers refer to Test Methods D1464 and .
1.3 The values stated in SI units are to be regarded as standard. No other units of measure 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 and health practices and determine the applicability of regulatory limitations prior to use.
