1.1 This practice covers procedures for taking a lot sample, at the source, of cotton fibers and reducing this sample through a series of steps to provide a relatively small test specimen of loose cotton fibers, representative of the source material and suitable for the determination of a single property, or a series of fiber properties, according to established procedures.
1.2 This practice has been used extensively for commercial acceptance testing of cotton fibers as well as for arbitration testing and research.
1.3 The procedures do not cover the selection of samples for the determination of moisture. Special handling and protection of the sample from the prevailing atmosphere required for samples taken for the determination of moisture are not provided for in this practice. See Test Method D 2495. Note 1This practice is used in taking samples of cotton for testing by Test Methods D 1440, D 1442, D 1445, D 1447, D 1448, D 1464, D 2480, D 2496, and D 2812.
