标准简介
适用范围:
This test method may be used for acceptance testing of commercial shipments of textile fibers, however caution is advised because information about between-laboratory precision is incomplete. Comparative tests as directed in 5.1.1 may be advisable. See Section 13 for single-laboratory information.5.1.1 If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, use the samples for such a comparative tests that are as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing and randomly assigned in equal numbers to each laboratory. The test results from the laboratories involved should be compared using a statistical test for unpaired data, a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results for that material must be adjusted in consideration of the known bias.This test method is applicable to all single fibers. Due to variability of individual fiber shrinkage, it is recommended that a large number of fibers of the same material be tested to reduce errors in estimating shrinkage.Results obtained by this test method can be used for the following purposes:5.3.1 As an aid in predicting the dimensional stability of fabrics to wet processing,5.3.2 As an aid in predicting the dimensional stability of fabrics during processing at elevated temperatures, and5.3.3 As a control measure in the manufacture of some types of fibers.1.1 This test method covers the measurement of the shrinkage of crimped or uncrimped single staple fibers when exposed to hot air or to near the boiling point of water.Note 1—For shrinkage of fibers by the bundle test, refer to Test Method D 2102.1.1.1 This test method is also used on staple fibers and filaments removed from tow or yarn.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in either system are not exact equivalents; therefore, each system must be used independently of the other.1.3 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.
