Servo Hydraulic Universal Testing Machine 2000kN rebar tensile test ISO6892 ASTM E8 CS2 HUT206DP
Wance HUT-DP series uses side action hydraulic grips for specimen clamping. The hydraulic side-acting grips provide an innovative solution for high-capacity testing and deliver enhanced gripping performance, usability, and operator safety over traditional grip designs. These advanced grips maintain a constant clamping force on the specimen that acts perpendicular to the direction of testing and is independent of tensile loading.
CS2 - Steel Reinforcing Bars for the Reinforcement of Concrete
CS2:2012 was published under the authority of the Standing Committee on Concrete Technology (SCCT) in November 2012. It supersedes CS2:1995, which was first published in August 1995.
6.4 TENSILE TEST
6.4.1 Test equipment
The force-measuring system of the testing machine shall be calibrated to at least Class 1 in accordance with ISO 7500-1:2004. The extensometer shall be calibrated to at least Class 1 in accordance with ISO 9513:1999 for the determination of Rp0.2; for the determination of Agt, a Class 2 extensometer (see ISO 9513:1999) can be used.
6.4.2 Test procedure
The tensile test shall be carried out in accordance with Cl. 10 of BS EN ISO 6892-1:2009.
For yield strength of grade 500 steel reinforcing bars, the upper yield strength (ReH), which is the maximum value of stress prior to the first decrease in force, shall apply.
If a yield phenomenon is not present, the yield strength from 0.2% proof strength (Rp0.2)
shall be determined in accordance with Appendix A. For grade 250 steel reinforcing bars, the yield strength shall be determined from the 0.2% proof strength (Rp0.2).
For determination of percentage total elongation at maximum force (Agt), test shall be carried out in accordance with Appendix B.
The mechanical properties of the test specimen including upper yield strength (ReH) or 0.2% proof strength (Rp0.2), tensile strength (Rm) and the percentage total elongation at maximum force (Agt) shall be determined in tensile test. The nominal cross-sectional area (An) of the test specimen shall be used for calculating the tensile properties (ReH or Rp0.2, Rm) unless otherwise specified in the relevant product standards.
