Quality and traceability


LEA’s quality system meets requirements of French and international standards.

LEA is:

  •     ISO 9001 certified (certificate 2019/83489.1);
  •     COFRAC* accredited (for calibration in the field of ionizing radiation; NF EN ISO/IEC 17025: 2017, scope N°2-6386 available on www.cofrac.fr or upon request).

LEA is accredited by COFRAC, France’s accreditation body signatory to ILAC MRA** in the field of calibration of ionizing radiations, in accordance with ISO 17025:2017. LEA’s traceability to the International System of Units (SI) is performed through calibrations with LNHB (Laboratoire National Henri Becquerel), France’s National Metrology Institute (equivalent to NIST in the US). LNHB is also accredited by COFRAC in the field of calibration of ionizing radiations. Both NIST and LNHB are signatories to CIPM-MRA***, meaning NIST and LNHB mutually recognize the validity of their calibrations and certificates. Therefore, through both COFRAC accreditation and calibrations traceable to LNHB, LEA certificates provide the same traceability to SI as NIST traceable certificates.

  •     Our radiation protection management system is certified according to the order of November 27.2013 relating to companies operating in establishments carrying out nuclear activities by the Qualianor organization (certificate No.296-R).

Therefore, every year several internal and external audits are carried out by independent organizations and contribute to ensure optimal quality.
