scope:

This guide provides model test methods for determining the short- and long-term mechanical properties of FRP reinforcing bars, grids, tendons, and laminates-both prestressed and nonprestressed-for concrete and masonry structures. As noted in the individual methods, most of the methods for bars are also suitable for sections cut from grids. Where necessary, the tests consider the bars and laminates tested embedded in or bonded to concrete or masonry. For the most part, however, these tests are considered to be material tests and not component or structural tests.

These model test methods are intended for consideration, modification, and adoption, either in whole or in part, by a U.S. national standards-writing agency such as ASTM International or AASHTO. The publication of these test methods by ACI Committee 440 is an effort to aid in this adoption.

The guide contains only test methods and not material standards. The individual test methods contained in this guide do not specify minimum material properties that must be met for the materials to be considered acceptable for use. Guidance on deciding whether a material is acceptable based on test results is made in the material specifications and design provisions that complement these test methods (ACI 440.1R; ACI 440.2R; ACI 440.6).

The test methods presented in this guide are the recommendations of ACI Committee 440, and have not been adopted by ACI as standards. As such, they are, for the most part, written in nonmandatory language, using "should" and "may" rather than "shall" and "must." In keeping with the usual test method format, however, some language is imperative ("Fill a cylinder with water..." rather than "A cylinder should be filled with water..."). Although typically considered to be mandatory language, the use of imperative language in these test methods is for readability, and remains as committee recommendations only.
