IPC-4412A  covers the classification and requirements for finished fabrics woven from "E" glass fiber yarns. These yarns are formed from filaments of electrical-grade glass and are intended as reinforcing materials in laminated plastics for electrical and electronic uses. The fabrics covered by this specification are all of a plain-weave construction. Includes two extensive tables of finished fabric glass styles, one in SI units and the other in US units. Supersedes IPC-4412, IPC-EG-140 with Amendments 1 and 2 and, in turn, IPC-EG-140. 19 pages. Released January 2000.
