Proving Tensile Strength of Re Bar is Changing



Testing rebar for strength and performance is changing, the need for total strain at break as a result and the obvious safety risks when traditionally removing extensometers (the strain measuring device) at yield before a bar breaks for example at 150 tons force, has driven the development of a new 500mm Field Of View non contacting optical extensometer. At Tinius Olsen we have integrated the new Epsilon optical extensometer into our model SL 1000kN and 2000kN Horizon software-based rebar tensile test systems, this means;


  • Automatic calculation of strain % at break
  • No user hands near the test specimen during the test
  • and if required strain rate control of the test


Job done!
