    Significance and Use

    5.1 Apparent shear strength determined by this test method is useful for quality control and specification purposes. It is also applicable to research and development programs concerned with interlaminar-shear strength. The apparent shear strength obtained by this test method is not intended for design purposes, but allowed to be utilized for comparative testing of composite materials, if all failures are in horizontal shear.

    5.2 It is recommended that control samples be fabricated with each research test series and that care be used to compare each set of controls with corresponding test series run at different times.

    1. Scope

    1.1 This test method covers the determination of the apparent horizontal shear strength of fiber reinforced plastic rods. The specimen is a short beam in the form of lengths of pultruded rods. This test method is applicable to all types of parallel-fiber-reinforced plastic rod samples.

    1.2 This test method is primarily used for quality control and specification purposes (see 5.1).

    1.3 The values stated in SI units are to be regarded as standard.

    1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    Note 1: There is no known ISO equivalent to this standard.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
