Used to extrude the rock sample.
Standards ASTM D7981
Used to extrude the rock sample from its jacket thus avoiding to empty the confining fluid. It consists of a steel frame with a rack and pinion mechanism. Supplied without adapters. See the following table

Used for indirect tensile test (splitting test).
Standards ASTM D3967 ISRM
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.

Used for compression test according to ASTM D7012
Standards ISRM ASTM D7012
Compression device for rock core specimens with dia. from 54.7 mm (NX) to 63.5 mm (HQ) conforming to ASTM D7012.
They provide a very accurate electrical signal, strictly proportional to the strain of the specimen
Standards ASTM D5407 ASTM C469 ISO 6784 DIN 1048 UNI 6556 BS 1881:121 EN 13412 EN 12390-13
They provide a very accurate electrical signal, strictly proportional to the strain of the specimen submitted to load application, for determining the Elastic Modulus and strength characteristics as alternative to the Compressometer-Extensometers 55-C0222/G which can be used only on samples with min dia.75mm and min height 160mm. They can be applied to the specimen surface by a special Adhesive-Catalyst agent and other accessories all included in the 82-P0399/C Strain gauge application kit.
Up to 4 strain gauges ¼ bridge, and up to 8 ½ bridge, can be directly connected by one or two interfaces 82-P0398 to to our automatic control consoles MCC or Automax Multitest which are suitable for cyclic loading and automatic determination of the Modulus of Elasticity.
Strain gauges can also be connected, by one or two interfaces 82-P0398, to a suitable data logger as, for example, our model 82-P9008, when the load application on the specimen is performed with Automatic compression testers as, for example the AUTOMAX PRO and PILOT PRO models. In this case, one of the channels of the Datalog 82-P9008 should be used for the load signal coming from an additional pressure transducer with selecting valve fitted to the compression tester.
