ASTM D7018/D7018M-12

Standard Terminology Relating to Glass Fiber and Its Products (Withdrawn 2021)

SCOPE
1.1 This standard is a compilation of terminology developed by Committee D13.18 on Glass Fiber and its Products.
1.2 This terminology is unique to glass fibers, strands, yarns, fabrics, etc. in the glass textile industry. Terms that are generally understood or adequately defined in other readily available sources are not included.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 Subcommittee D13.18 has jurisdictional responsibility for standards and terminology in this standard. Any change in wording requires the approval of D13.18 subcommittee. Any changes approved by the subcommittee and main committee are then directed to subcommittee D13.92 on Terminology for inclusion in Terminology D123.
WITHDRAWN RATIONALE
This standard is a compilation of terminology developed by Committee D13.18 on Glass Fiber and its Products.
Formerly under the jurisdiction of Committee D13 on Textiles, this terminology was withdrawn in January 2021 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
