Active view current version of standard. Other Historical Standards. More D It also covers textured glass fiber yarns. This specification is intended to assist ultimate users by designating the general nomenclature for the strand products that age generally manufactured in the glass fiber industry. General applications are identified by means of a letter designation. The letter designation represents a family of glasses that have provided acceptable performance to the end-user in the intended application.

For example, the composition limits stated for E-Glass in this specification representing the glass fiber family for general and most electrical applications is designated by the letter E. Military specifications, such as, MIL-R, recognize the composition limits described in this specification as meeting the respective requirements for E-Glass strands used in reinforced plastic structure applications.

Property requirements under specific conditions are agreed upon between the purchaser and the supplier. Electrical property requirements vary with specific end-use applications. For printed circuit board applications, other requirements may be needed such as the use of Institute for Interconnecting and Packaging Electronic Circuits IPC Specification EG A for finished fabric woven from E-Glass for printed circuit boards, or Specification MIL-P for printed wiring boards applicable to glass fabric base.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. These include finished glass fabrics, unfinished glass fabrics, glass tapes, glass sleevings, glass cords, glass sewing threads, and finished laminates made from finished glass fabrics.

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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Standard Specification for Glass Fiber Strands

GFRP is now a viable option in the replacement of reinforcing steel for bridge decks. Additive : A material added to another material to improve the properties of the latter or to improved the manufacturing process. Bar : a non-prestressed FRP element with nominally rectangular or circular cross- section, used to reinforce a concrete component. The bar can be an independent bar or part of a grid. May be deformed, sand coated, or use other methods to achieve minimum bond strength requirements. Cure: the process of causing an irreversible change in the properties of a thermosetting resin by chemical reaction. Glass Transition Temperature Tg : the midpoint of the temperature range over which an amorphous material changes from a brittle and vitreous state to a plastic state, or visa versa.
