Standard Test Method for Flexural Strength of Hydraulic-Cement Mortars1
1. Scope
1.1 This test method covers the determination of the flexuralstrength of hydraulic-cement mortars.
1.2 The values stated in sl units are to be regarded asstandard. No other units of measurement are included in thisstandard.
1.3 Values in Sl units shall be obtained by measurement inSl units or by appropriate conversion, using the Rules forConversion and rounding given in Standard IEEE/ASTM SI10.of measurements made in other units.
1.4 This standard does not purport to address all of thesafety concerns. if any, associated with its use已复responsibility of the user of this standard to estabish appro-
priate safety. health. and environnental practices and deter-mine the applicabiliry of regulatory limitations prior to use.Warning-Fresh aydraulic cementitious mixtures are causticand may cause chemical burns to skin and tissue uponprolonged exposure.2
1.5 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) Comnittee.
