Dry strength is measured by supporting a bar on two points and applying an increasing force from above at the mid point until failure occurs. A formula into which the span, force and diameter of the bar are substituted yields the drying strength.
See DSRN and DSTR tests for more info.
Round or square fired bars are subject to a force that tests their tensile strength. The strength can be calculated from the force and the dimensions of the cross section where the break occurred.
