適用范圍：This European Standard specifies several methods for preparing laboratory samples of fibres, yarns or fabrics and presents a limited treatment of the problem of drawing specimens for testing. The principle of each method is given at the beginning of the clause dealing with the method. It is not possible for the coverage of each individual procedure to be fully comprehensive; in many instances, the selection of test samples or test specimens is necessarily covered by the appropriate method of test. The selection of length-biased samples is not within the scope of this standard, nor are particular procedures for determination of commercial weights or moisture content. Annex A and the tables are given in this standard for general guidance in determining the size of the test sample to be taken in order that the determined sample mean has given confidence limits.
