Dry strength test
WebDS - Dry Strength (kgf/cm2) Test. 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. Webstrength when air dry.
