The desired results aatm that modulus of rupture is calculated and the specimen fails within the middle third of the span length in the tension area or underside of the specimen.

Email addresses must contain the symbol. How can we help you? Satisfies the requirements of both ASTM C and C78 Rated to kN 22, lbf Loading span attached to a spherical seat to maintain proper alignment Includes preinstalled metric ruler to ease specimen placement. Link to Active This link will always route to the current Active version of the standard.

ASTM C 78 C determines the flexural strength of concrete by the use of a simple beam with third-point loading. The DX is a servo-controlled system, which allows the test to perform automatically within a closed loop.

The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Universal materials testing software for static hydraulic, electromechanical and torsion testing systems – WBB. It is the responsibility of the user of this standard to adtm appropriate safety, health, and environmental practices asym determine the applicability of regulatory limitations prior to use.

For the same specimen size, the atsm determined will vary if there are differences in specimen preparation, curing procedure, moisture condition at time of testing, and whether the beam was molded or sawed to size.
