EN STANDARD – HIGH STABILITY COMPRESSION MACHINES

The compression testing machines tested for high stability meet the stringent requirements of the: EN 12390-4 | BS 1881:115 | DIN 51220 | UNI 6686, part 3 | NF P18-411 | UNE 83304 | ASTM C39 | AASHTO T22

These four columns prestressed frames are manufactured with specific quality features (processing, tolerances), piston/cylinder group, spherical seat, compression platens, distance pieces etc., conforming and meeting the high stability verification (force distribution).

The conformity of the stability is certified with the verification of the self-alignment (foot-meter test) of the machines components and the restraint on movement of the upper spherical seat/platen, by using a special electric strain load column at 5 measuring points which is connected to its suitable datalogger.
The most important feature of the high stability frames is their uniform distribution of the applied load on all the specimen surface under test. The sample breakage is satisfactory and the strength results are correct, high and true.
