ASTM D4849-13

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

1. Scope
1.1 This standard is a compilation of terminology developed by Committee D13.58 on Yarns and Fibers.
1.1.1 This terminology, mostly definitions, is unique to fibers and yarns used in the textile industry. Terms that are generally
understood or adequately defined in other readily available sources are not included.
1.1.2 Subcommittee D13.58 has jurisdictional responsibility for every item in this standard. The standards in which the terms
and definitions are used are listed by number after the definition. The wording of an entry cannot be changed without the approval
of 13.58 subcommittee. Any changes approved by the subcommittee and main committee are then directed to subcommittee
D13.92 on Terminology for subsequent changes or additions to Terminology D123.
1.1.3 This terminology standard is not all inclusive of the terms under the jurisdiction of Subcommittee D13.58. Other
terminology standards under the jurisdiction of Subcommittee D13.58 are D3888, D4466, and D4848.
