NBN EN 12751:1999

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.
