1.1 This test method covers the measurement of the average length and length distribution of fibers in wool top, on a mass-biased basis. The method is applicable to all types of fibers in sliver formed from long parallelized fibers. Note 1--The determination of fiber length of wool is covered in Test Method D1575, Test Method for Fiber Length of Wool in Scoured Wool and in Card Sliver, the staple length of grease wool is covered in Test Method D1234, Test Method of Sampling and Testing Staple Length of Grease Wool. Note 2--This test method specifically requires length in inches and mass in SI units and is not contrary to ASTM policy. The SI units in parentheses are provided for information only. 1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
Knowledge of the average fiber length and the distribution of fibers is of primary importance to users of top in further processing. Acceptance specifications for the fiber length and length distribution may be established by the user based on the type of yarn-making equipment employed and the desired end uses. Test Method D 519 for testing wool top for fiber length is considered satisfactory for acceptance testing of commercial shipments since the method has been used extensively in the trade for acceptance testing and the current estimates of the between-laboratory precisions are acceptable. In case of a dispute arising from differences in reported test results when using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative testing to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogenous as possible and that are from a lot of the type material in question. The test specimens should then be assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student's t-test for unpaired data and an acceptable probability level chosen by the two parties before testing is begun. If a bias is found either its cause must be found and corrected or the purchaser and supplier must agree to interpret future test results in the light of the known bias.

Test Method D 1770 for the determination of neps, vegetable matter, and colored fiber may be used for the acceptance testing of commercial shipments of wool top but caution is advised because the between-laboratory precision is known to be poor. Comparative tests as directed in 5.1.1 may be advisable. 5.1.1 In case of a dispute arising from differences in reported test results when using Test Method D 1770 for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between their laboratories. Competent statistical assistance is recommended for the investigation of bias. As a minimum, the two parties should take a group of test specimens that are as homogeneous as possible and that are from a lot of material of the type in question. The test specimens should then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared using Student’t-test for unpaired data and an acceptable probability level chosen by the two parties before the testing is begun. If a bias is found, either its cause must be found and corrected or the purchaser and the supplier must agree to interpret future test results in the light of the known bias.1.1 This test method covers the determination of the number of neps and pieces of vegetable matter by size classes, and the number of colored fibers, in 15 g samples of wool top.1.2 This test method is applicable to wool top in any form. Note 1 - For the determination of number of neps per specified mass of cotton samples, refer to Test Method D 1446.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 and health practices and determine the applicability of regulatory limitations prior to use.
