1、Designation:D578/D578M05(Reapproved 2011)1Standard Specification forGlass Fiber Strands1This standard is issued under the fixed designation D578/D578M;the number immediately following the designation indicates the yearof original adoption or,in the case of revision,the year of last revision.A number
2、 in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.1NOTEEditorial changes were made throughout in August 2011.1.Scope1.1
3、This specification covers the requirements for continu-ous fiber and staple fiber glass strands,including single,pliedand multiple wound.It also covers textured glass fiber yarns.This specification is intended to assist ultimate users bydesignating the general nomenclature for the strand productstha
4、t age generally manufactured in the glass fiber industry.1.2 Glass fibers are produced having various compositions.General applications are identified by means of a letterdesignation.The letter designation represents a family ofglasses that have provided acceptable performance to theend-user in the
5、intended application.For example,the compo-sition limits stated for E-Glass in this specification representingthe glass fiber family for general and most electrical applica-tions is designated by the letter E.Military specifications,suchas,MIL-R-60346,recognize the composition limits describedin thi
