Standard Test Method for Tensile Properties of Glass Fiber Strands, Yarns, and Rovings Used in Reinforced Plastics


1.1 This test method covers the determination of the comparative tensile properties of glass fiber strands, yarns, and rovings in the form of straight standard test specimens when tested under defined conditions of pretreatment, temperature, humidity, and tension testing machine speed. This test method is applicable to continuous filament, glass fiber materials that have been coated with a resin compatible sizing.

Note 1-There is no known ISO equivalent to this test method. Note 2-This test method was originally developed as a quality control test for glass fiber. It should not be used to develop composites design data. Consult Test Method D638, Test Method D3039/ D3039M, or the materials specification for development of composite design properties.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

Note 3-Prime consideration should be given to the use of a polymeric binder that produces specimens that yield the highest consistent values for the glass fiber material under test. Tensile properties may vary with specimen preparation, resin impregnation system, and speed and environment of testing. Consequently, where precise comparative results are desired, these factors must be carefully controlled.

1.3 This standard does not purport to address all of the safety concerns, 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.
