A document reporting the results of calibration. A Laboratory issuing it does not require an accreditation and doesn’t need to conform to the requirements of any standard. Because of this, it is not a document considered valid for the purposes of satisfying the requirements of certified Management Systems. In particular, it does not guarantee traceability to national and international standards.
Furthermore, it does not guarantee the competence of the organisation that issues it, and obliges the end user to carry out an assessment of the supplier of the calibration report.
