标准简介

适用范围：

5.1 The reliability of the results of any test method depends primarily upon how well the specimens tested represent the original source material or lot. Failure to provide a test specimen which accurately represents the lot from which it is drawn will produce misleading test results regardless of the accuracy and precision of the test method.1.1 This practice covers procedures for taking a lot sample of cotton fibers, from a designated source (lot), and reducing the lot sample through a series of steps to produce test specimens that are representative of the source and suitable for the determination 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.NOTE 1: This practice is used in taking samples of cotton for testing by Test Methods D1440, D1442, D1445, D1447, D1448, D1464, D2480, D2812, D5866 and D5867.1.3 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 D2495.1.4 The values stated in SI units are to be regarded as standard. No other units of measure are included in this standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
