CIRAM: an accredited, independent and recognized laboratory

ISO-IEC 17025 accreditation*, issued by COFRAC, is the international benchmark for testing and calibration laboratories. It attests to their technical competence, the validity of their methods, and the reliability of their results. Unlike method standards that define how to measure a parameter, ISO-IEC 17025 certifies that the laboratory itself is capable of performing its analyses under strictly controlled, auditable, and reproducible conditions.

In Martillac, near Bordeaux, CIRAM is accredited ISO/IEC 17025* for the stable isotopic analysis of carbon and nitrogen and the graphitization of organic materials. This site, unique in France, was designed to accommodate sensitive and complex analyses in a secure scientific environment. This official recognition reflects our daily commitment: to provide our clients with reliable, reproducible, and trustworthy results.

Certified and controlled analysis methods

At CIRAM, we employ rigorous and recognized methods to guarantee the reliability of results. Our analyses are based on stable carbon and nitrogen isotope analysis, graphitization, and radiocarbon dating by accelerator mass spectrometry (AMS), for precise and reproducible measurements.

The main international standards for biobased content analysis of materials:

  • ASTM D6866: American standard, measurement of biobased carbon by radiocarbon analysis
  • EN 16640: European standard, determination of biobased carbon by the C14 method
  • ISO 16620-2: biobased content in plastics
  • EN 16785-1: calculation of the biobased total percentage of a product
  • ISO 21644: method for measuring biobased carbon in CSR

This expertise guarantees reliable, readable results that comply with the requirements of industry sectors.
