ASTM C 1399 determines the slow crack growth parameters of advanced fiber-reinforced concrete by using constant stress-rate flexural testing in which flexural strength is determined as a function of applied stress rate in a given environment at ambient temperature.

The universal test machine must be capable of controlling the rate of motion of the loading head and meeting the requirements of Test Method ASTM C1399. A load rating of 10,000 lbf will generally be required. By means of our testing expertise and modular product design, we will help find the testing solution that is right for you.
