1.1 This test method covers the determination of residual strength of a fiber-reinforced concrete test beam. The average residual strength is computed for specified beam deflections beginning after the beam has been cracked in a standard manner. The test provides data needed to obtain that portion of the load-deflection curve beyond which significant cracking damage has occurred and it provides a measure of post-cracking strength, as such strength is affected by the use of fiber-reinforcement.

1.2 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.

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