# DS - 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.

### Fired strength tester

Tap picture for full size and resolution

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.

VAL - Value (V)
