4、l requirements for wovenroving glass fiber fabrics. This specification permits the appli-cation of sizing materials to the glass fiber roving duringmanufacture that helps facilitate weaving. When used aspermitted in this specification, such materials are compatiblewith the resin matrix as specified
5、in the contracting instrument.NOTE 1Sizing materials on glass fiber yarns, in most cases, areremoved by various cleaning procedures as a first stage in preparing afinished fabric. When these yarn sizing materials are removed during acleaning procedure, they need not be compatible with the subsequent

Classification4.1 Designation of Woven Roving Fabric The basic des-ignations for glass woven roving fabric is by mass per unit areaand i
17、s given in grams per square metre (ounces per squareyard). Historically, anASTM type number has been used by theindustry. These numbers have been sequentially assigned asnew woven roving constructions as they were added to thisspecification. Numbers, 1 through 10, are shown in Table 1with the relati
18、onship to mass per unit area and fabric count.REQUIREMENTS5.

24、ng fabrics listed in Table 1, the averagemass per unit area shall conform to the requirements of Table1. For woven roving fabrics not listed in Table 1, the averagemass per unit area shall be agreed upon between the purchaserand the supplier. The average mass per unit area for the lot shallbe within
25、 the interval: specified mass per unit area 6 10 % ofthe specified mass per unit area.13. Width13.1 Fabric width shall be agreed upon between the pur-chaser and the supplier. The fabric width, including bothselvages but excluding any feathered edges, shall not be lessthan the specified width and no
26、more than 13 mm (0.5 in.)wider than the specified width.NOTE 3During the processing of glass fabrics, the selvages may beslit to minimize tension influences. This slit distance is excluded whenmeasuring the fabric width unless otherwise agreed upon between thepurchaser and the supplier.14. Length14.
