    Significance and Use

    5.1 This test method is not recommended for acceptance testing due to its poor between-laboratory precision. In some cases the purchaser and the seller may have to test a commercial shipment of one or more specific materials by the best available method even though the method has not been recommended for acceptance testing of commercial shipments. In such a case, if there is a disagreement arising from differences in values reported by the purchaser and the seller when using this method for acceptance testing, the statistical bias, if any, between the laboratory of the purchaser and the laboratory of the seller should be determined with each comparison being based on testing specimens randomly drawn from one sample of material of the type being tested.

    5.2 A knowledge of the average length and length distribution of fibers is important to fiber processors. This method is useful for inplant control testing and for research purposes.

    1. Scope

    1.1 This test method covers the estimation of the average fiber length and length distribution of wool in nonparallel assemblies, such as scoured wool, and in card sliver.

    1.2 This test method is applicable to many fibers other than wool if in the form of a nonparallel assembly or in a card sliver.

    1.3 This test method is not applicable to unscoured wool or to wool top.

    1.4 This test method specifically requires length in inches and mass in metric units, and is not contrary to ASTM policy. The values stated in inch-pound units are to be regarded as the standard. The information in parentheses is for information only.

    Note 1The determination of staple length of grease wool is covered in Method D1234, Sampling and Testing Staple Length of Grease Wool,2 and the average length of fibers in wool top is covered in Test Method D519.

    1.5 This standard does not purport to address 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.
