The CERIB laboratory has COFRAC testing accreditation No. 1.0001 for verification of tensile/compressive-strength testing machines in accordance with relevant standards (NF EN 12390-4 for concrete and construction materials, NF EN ISO 7500‑1 for metallic materials).
(scope available at www.cofrac.fr)

Every regional technician can work on-site to control testing machines.

Range covered:

  • tensile strength: up to 300 kN
  • compressive strength: up to 6,000 kN.

Types of apparatus calibrated:

Testing machines, strain cylinder for verifying the self alignment of the upper platen (force transfer)
Production presses.

Technical equipment used by our metrology teams:

– calibration dynamometers: from 20 kN to 6,000 kN
– standard weights
– strain cylinder (Foote meter) for ball-joint verification as per concrete materials standard
– equipment for verifying platen hardness
– data acquisition system for loading rates.
