1、Designation: D7018/D7018M 11Standard Terminology Relating toGlass Fiber and Its Products1This standard is issued under the fixed designation D7018/D7018M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision. A
2、 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 developedby Committee D13.18 on Glass Fiber and its Products.1.2 This terminology is uni
3、que to glass 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 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard. The valu
4、es stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.4 Subcommittee D13.18 has jurisdictional responsibilityfor standards and terminology in this sta

9、midity of at least 48 % and no greater than67 %, 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
10、 these materials requiredifferent testing 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 asspec
11、ified in Specification E171. It is the 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,anund
