Additional Information

Verification of force transfer
The conformity of the compression tester to the EN 12390-4 requirements in terms of stability (force transfer) is performed by the verification of the self-alignment of machine components and the restraint on movement of the upper platen.
The compliance of all our EN testers to these stringent requirements is precisely verified using specific apparatus (82-E0105/1 and 82-P0804/E). An incorrect load application may cause premature sample failure and, consequently the resultant strength could be significantly lower than the true resistance.
