Brazilian Tensile Test Apparatus

岩石巴西劈裂试验装置

Brazilian Tensile Test Apparatus — Rock Mechanics Equipment

Rock is weakest in tension, and direct pull tests are hard to run, so the Brazilian disc test is the standard way to measure tensile strength indirectly. We offer curved-jaw jigs for NX discs, adjustable flat-platen jigs, a large jig for 100–150 mm discs, a digital tester with its own frame and a servo machine for displacement-controlled tests. Disc diameter and whether you already own a compression machine decide the choice. Results are normally reported under ASTM D3967 or, in India, IS 10082.

How to specify

  1. Confirm whether your method calls for curved jaws or flat platens with bearing strips.
  2. A jig fitted to your existing compression machine is the lowest-cost option.
  3. Use a load range low enough to resolve failure loads of a few kilonewtons.
