- The supporting and loading rollers have diameter in the range of 30 mm. They extend on both sides beyond the dimensions of the specimens by more than 10 mm.
- The distance from centre-to-centre of the two supporting rollers is adjustable to the overall length of the specimen minus 50 mm.
- The loading roller is arranged for application of load from the top of the specimen along the vertical center line between the supporting rollers.
- If automatic CTM is selected, the flexural strength of the sample will be calculated automatically. But if CTM with manual pace rate control is selected, the calculation of the flexural strength has to be calculated manually.
