ASTM D 4029 : 1997

1.1 This specification primarily covers finished fabrics woven from "E" electrical glass fiber yarns that are intended primarily as a reinforcing material in laminated plastics for structural use. This specification can also be applied to fabrics made of glass fiber types as agreed upon between the purchaser and the seller.

1.2 This specification specifies the terminology, definitions, general requirements, and physical requirements for woven glass fiber finished fabrics. This specification permits the application of sizing materials to the glass fiber yarn during manufacture that helps facilitate weaving. When used as permitted in this specification, such materials are compatible with the resin matrix as specified in the contracting instrument.

1.3 This specification shows the values in both inch-pound units and in SI units. "Inch-pound units" is the technically correct name for the customary units used in the United States. "SI" units is the technically correct name for the system of metric units known as the International System of Units. The values stated in either acceptable metric units or other units shall be regarded separately as standard. The values expressed in each system may not be exact equivalents; therefore each system must be used independently of each other, without combining values in any way.

1.4 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
