Chances are it is not accredited. Laboratories accredited by an accreditation body that is a signatory of the ILAC mutual recognition arrangement (MRA) have been assessed to all the requirements of ISO/IEC 17025. This means all aspects of the management and calibration processes were evaluated. This evaluation includes traceability, measurement uncertainty (MU), use of acceptable methods, environmental controls, results, reporting, and many other factors. It also includes a complete review of the management system of the laboratory. As a signatory of the ILAC MRA, ANAB can accept for calibration traceability only laboratories that have been accredited by an MRA signatory accreditation body. We trust that they have done as good a job as we would in assessing a laboratory's capabilities.
