This method covers the determination of the ultimate tensile strain capacity of concrete subjected to static and sustained flexural loading. It is especially applicable to mass concrete and the specimen dimensions are such as to facilitate testing mass concrete.

This method of test covers procedures for determining the planeness and parallelism of the ends of cylindrical test specimens and the perpendicularity of the sides to the ends. I t is intended for use in connection with the preparation of test specimens o f concrete, mortar, rock, and similar materials for test for compressive strength or other properties.
