Sediver Research Center laboratories obtained certification and accreditation recognized by more than 70 organisms in over 50 countries around the world.

C.E.B High Voltage laboratory is ISO 17025 certified, accredited by COFRAC - which ACCREDITATION CERTIFICATE is updated periodically. The scope is available on www.cofrac.fr In terms of testing, accreditation guarantees that the results are obtained according to valid methods and procedures that comply with precise standards. In terms of calibration, accreditation recognizes the aptitude of a laboratory to carry out calibrations and metrological verifications in a defined domain and with specified uncertainties. The Cofrac label on the calibration certificate guarantees the traceability of measurements in the International System of Units (SI).

COFRAC is signatory of multilateral international agreement and is recognized in over 50 countries around the world.
