For the bending tensile strength test according to standards on:
- concrete bars
- concrete beams
- concrete kerb stones
- concrete paving stones
- natural stone paving stones
- natural stone
- natural stone kerb stones
- Test machine frame with very sturdy 3-column C-frame model. The double-action test cylinder is installed at the top of the machine frame.
The load is measured via an electronic load cell which is is insensitive to lateral force; it is mounted at the top in the direct line of force.
