Strength and Ductility (The Tensile Test)

This is the most important test rebar undergoes. A sample bar is pulled apart by a powerful machine to measure three critical properties:

Toughness (Bending and Rebending Tests)

On a construction site, rebar must be bent into various shapes to form the reinforcing “skeleton.” Quality rebar must be tough enough to handle this without being damaged.

The Grip (The Pull-Out Test)

The ribs on deformed rebar are essential, but they must provide a proper grip. In this test, a piece of rebar is cast into a concrete block. After the concrete hardens, a machine pulls on the rebar to see if it slips. The standards specify a maximum allowable slip (just 0.2 mm), ensuring the bar will bond tightly with the concrete and won’t pull out under pressure.

Maximum Longitudinal Rib Height

According to the standard, the height of longitudinal ribs cannot exceed 10% (0.10) of the nominal bar diameter.

Transverse Rib Spacing Requirements

The spacing for transverse ribs must be greater than or equal to 40% (0.4) of the diameter and less than or equal to 120% (1.2) of the diameter.
