Standard Test Method for Flexural Strength of Concrete (Using Simple Beam withThird-Point Loading).
1.Scope*
1.1 This test method covers the determination of the flexuralstrength of concrete by the use of a simple beam withthird-point loading.
1.2 The values stated in either Sl units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.
1.3 This standard does not purport to address all of thesafety concerns，if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety,health， and environmental practices and deter-mine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards，Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Committee.
