This specification covers rail-steel and axle-steel deformed bars for concrete reinforcement. The standard sizes and dimensions of deformed bars and their number designation are presented. The carbon determination, deformation requirements and deformation measurement are provided. The material shall conform to the requirements prescribed by the specification. The yield point or yield strength shall be determined by either drop of the beam or halt in the gage of the testing machine, or by extension under load using an autographic diagram method. For all bar sizes a tension test, a bend test and a set of dimensional property tests including bar weight and spacing, height, and gap of deformations shall be made from each lot of 10 tons.
