Description

We propose two compression device models for indirect tensile test (splitting test) conforming to ASTM D3967 and to ISRM Specifications.
 
Model conforming to ASTM D3967
This apparatus, originally developed for testing in compression cement specimens, can also be used for splitting tensile test on rock disks with dimensions from dia 54 mm to 64 mm.

Models conforming to ISRM specifications
These models consist of two steel loading jaws, guiding pins and half ball bearing. Two models are available according to the specimens size: NX type (dia. 54.74 mm) and HQ type (dia. 63.5 mm).

All models can be used as an accessories with a suitable universal tester as UNIFRAME Compression / flexural machine.
