Our facilities are implemented during the phases of development and realization tests, and to conduct studies and tests for businesses and organizations either as services or joint projects.
  • Furnaces and experimental resources that can be adapted to each requirement
  • Test booth compliant with the IEC standard
  • CNPP has a calorimetry hood that can be used to characterize the combustion of products or equipment:
  • Three large tests halls one of which covers 910 sq. m and a height of 24 m with a movable ceiling of 270 sq. m and a height of between 9 and 15 m
  • Containers for pool fires from 50 to 200 sq. m
  • Secure explosion area and metrology room sheltered from the effects of the explosion (Missiles / excess pressure)

  • Measurement of smoke opacity

To confirm the test results and ensure the reliability of our measurements for our customers, we have our own calibration laboratory. Metrology is an inseparable part of our business.
The requirements of the COFRAC ISO 17025 standard on metrology cover all of our activities. For this reason, all our calibration and test laboratories are subject to the same rigor, whether they are COFRAC accredited or not (Accreditation No. 1-0064, scope available on
  • Periodic checks and calibrations of measuring devices,
  • Connection to international standards,
  • Inter-laboratory comparisons,
  • Technology and regulatory monitoring,
  • Drafting of procedures.
In our activities, metrology covers many types of measurement such as:
  • Accelerometry
  • Acoustics
  • Chemistry
  • Flowmetering
  • Dimensions
  • Electricity
  • Force
  • Hygrometry
  • Weight
  • Pressure
  • Radiometry – Photometry
  • Thermal radiation
  • Temperature
  • Time - Frequency
  • Volume
