2、 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.1NOTEThe units statement was updated and 3.1.1 and the last line of Table 2 were added editorially in August 2010.1.Scope1.1 This
3、specification primarily covers glass fabrics wovenfrom“E”electrical continuous glass fiber rovings that areintended primarily as a reinforcing material in laminatedplastics for structural use.1.2 This specification specifies the terminology,definitions,general requirements,and physical requirements
4、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 in the contracting
