(Terminology)Standard Terminology Relating to Glass Fiber and Its Products
Standard Terminology Relating to Glass Fiber and Its Products
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.

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.

3. Terminology
3.1 Alphabetical listing of terms for which Subcommittee D13.18 has jurisdiction:
atmosphere for testing textiles, n—for glass, air maintained at a relative humidity of at least 48 % and no greater than 67 %, and
at a temperature of at least 20°C (68°F)[68°F] and no greater than 25°C (77°F). [77°F].
DISCUSSION—(as related to all D13.18 standards)—Glass textiles are used in various products such as reinforced plastics, mat-like material, tire
cords, electrical insulation, etc. Each of these materials require different testing atmospheres. It is the intent of this wide spread in testing atmosphere
to allow testing of glass textiles in respective laboratories where end product test atmosphere requirements differ. The test atmospheres for respective
products should be controlled as specified in Specification E171. It is the opinion of Subcommittee D13.18 that the physical properties cited in
respective specifications would not be affected by the range selected. In any event, the test atmosphere should be stated in the report.
