Where can I find an accredited calibration laboratory?

Refer to the national accrediting agency’s site (Cofrac in France www.cofrac.fr).

The EA also has a Europe-wide database at http://db.european-accreditation.org/.

The BIPM site contains the calibration capacities of the national metrology laboratories that have signed the MRA (http://kcdb.bipm.org/default_fr.asp).
