2、he year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard is a compilation of terminology developed by Committee D13.18 on Glass Fiber and its Products
3、.1.2 This terminology is unique to glass fibers, strands, yarns, fabrics, etc. in the glass textile industry. Terms that are generallyunderstood 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 s
4、eparately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.1.4 Subcommittee D13.18 has jurisdictional responsibility for sta
5、ndards and terminology in this standard. Any change inwording requires the approval of D13.18 subcommittee. Any changes approved by the subcommittee and main committee are thendirected to subcommittee D13.92 on Terminology for inclusion in Terminology D123.2. Referenced Documents2.1 ASTM Standards:2

Terminology3.1 Alphabetical listing of terms for which Subcommittee D13.18 has jurisdiction:atmosphere for testing textile
9、s, nfor glass, air maintained at a relative humidity of at least 48 % and no greater than 67 %, andat a temperature of at least 20C 68F and no greater than 25C 77F.DISCUSSION(as related to all D13.18 standards)Glass textiles are used in various products such as reinforced plastics, mat-like material
10、, tirecords, electrical insulation, etc. Each of these materials require different testing atmospheres. It is the intent of this wide spread in testing atmosphereto allow testing of glass textiles in respective laboratories where end product test atmosphere requirements differ. The test atmospheres
11、for respectiveproducts should be controlled as specified in Specification E171. It is the opinion of Subcommittee D13.18 that the physical properties cited inrespective specifications would not be affected by the range selected. In any event, the test atmosphere should be stated in the report.blocki
