1、Designation: D 7018 04Standard Terminology Relating toGlass Fiber and Its Products1This standard is issued under the fixed designation D 7018; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in p
2、arentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This standard is a compilation of terminology developedby Committee D13.18 on Glass Fiber and its Products.1.2 This terminology is unique to glas
3、s fibers, strands,yarns, fabrics, etc. in the glass textile industry. Terms that aregenerally understood or adequately defined in other readilyavailable sources are not included.1.3 Subcommittee D13.18 has jurisdictional responsibilityfor standards and terminology in this standard. Any change inword
4、ing requires the approval of D13.18 subcommittee. Anychanges approved by the subcommittee and main committeeare then directed to subcommittee D13.92 on Terminology forinclusion in Terminology D 123.2.

Terminology3.1 Alphabetical listing of terms for which SubcommitteeD13.18 has jurisdiction:atmosphere for testing textiles, nfor glass, air maintainedat a relative humidity of at least 48 % and no greater tha
8、n67 %, and at a temperature of at least 20C (68F) and nogreater than 25C (77F).DISCUSSION(as related to all D13.18 standards)Glass textiles areused in various products such as reinforced plastics, mat-like material,tire cords, electrical insulation, etc. Each of these materials requiredifferent test
9、ing atmospheres. It is the intent of this wide spread intesting atmosphere to allow testing of glass textiles in respectivelaboratories where end product test atmosphere requirements differ. Thetest atmospheres for respective products should be controlled asspecified in Specification E 171. It is th
10、e opinion of SubcommitteeD13.18 that the physical properties cited in respective specificationswould not be affected by the range selected. In any event, the testatmosphere should be stated in the report.blocking, nof coated fiber glass yarn solar screening,anundesired adhesion between touching laye
