Testing Mechanical Splices

What testing splices with Concrefy feels like

Testing mechanical splices and headed bars

Concrefy specializes in testing reinforcement couplers for mechanical splices in accordance with international standards for a wide range of applications.
For mechanical splices in reinforcing steel and headed bars, various international standards define specific requirements and testing procedures.
Concrefy is among a select group of laboratories worldwide capable of performing advanced testing for mechanical splices in reinforcing steel and headed bars. Based on static, dynamic and cyclic loading tests, we assess whether products meet the required performance criteria for applications such as bridges, viaducts, power plants, dams, high-rise buildings and stadiums.

Benefits

  • Extensive experience with international regulations and standards
  • Advanced testing equipment with capacities up to 1200 kN for tensile testing (rebar diameters up to 40 mm)
  • High-frequency fatigue testing using pulsator systems (tests completed in hours rather than days)
  • Accredited for a wide range of standard tests
  • Reports available online anytime

Tests and standards

When ISO 15835 tests have to be carried out, a combination of slip measurements with tensile tests, fatigue tests and low-cycle loading tests is often required. We routinely carry out these tests with a 1200 kN tensile and compression test machine (up to 40 mm bar diameter) and because we have high frequency pulsators (HFP) instead of hydraulic fatigue machines, a sample fatigue test takes only eight hours while hydraulic machines need an entire week for this test.

Possible tests on couplers & headed bars:

  • ISO 15835: slip, tension, fatigue and low cycle tension and compression tests
  • ISO 15698-2: tensile, wedge tensile test, high cycle fatigue, low cycle tension tests
  • ACI 359-01: tension, tension at -7°C, and cyclic tension tests (100 cycles)
  • AC133: static tension, static compression and cyclic tension and compression tests
  • TUC Rail 30.2: slip, tension, fatigue tests
  • NSW – SF2013/184115: slip, tension, fatigue tests
  • IS 16172: slip, tension, cyclic tensile test, high cycle fatigue tests
  • BS 8597: slip, tension, high cycle fatigue tests
  • Cares TA1-B: slip, tension tests
  • Cares TA1-C: slip, tension, compression, cyclic tension tests (100 cycles)
  • NF A35-020-2-1: slip, tension, fatigue and low cycle tension and compression tests
  • NF A35-020-2-2: slip, tension, fatigue and low cycle tension tests

Former projects & References

The tests to be carried out on mechanical splices depend on the type of construction, the country and the risk of earthquakes at the location where the construction is being built.
