All MSL reports are issued under the control of our quality system to ensure that the report has been produced following a validated technical procedure. In general you can assume that the endorsements on your report will be appropriate for your needs. If you have special requirements, particularly relating to international trade, you should discuss these with us before a work order agreement is signed.
MSL reports are issued with one of four covers that carry the relevant endorsements:
- Reference to the Measurement Standards Act
- Reference to the Measurement Standards Act and with an endorsement from IANZ on the basis of our accreditation to NZS/ISO/IEC 17025 as a testing laboratory
- Reference to the Measurement Standards Act and with an endorsement from IANZ on the basis of our accreditation to NZS/ISO/IEC 17025 as a calibration laboratory
- Reference to the Measurement Standards Act, an endorsement from IANZ on the basis of our accreditation to NZS/ISO/IEC 17025 as a calibration laboratory, and the CIPM MRA logo to indicate that the certificate is consistent with internationally recognised capabilities
All routine reports are endorsed as in 2 or 4.
The right to put a CIPM MRA logo on a calibration certificate is hard-earned. It means that MSL has participated successfully in an international comparison relevant to the quantities in the certificate, it will have demonstrated a track-record of research in the area and it will be accredited to NZS/ISO/IEC 17025 for the specific quantities based on assessments carried out by international scientific peers. The specific capabilities are listed on the BIPM key comparison database having been further scrutinised by experts from all the regional metrology organizations.
Overseas regulators are not always empowered within their jurisdiction to accept overseas calibration certificates. From time to time we are asked by repair and testing organisations accredited under the auspices of US authorities such as the Federal Aviation Administration (FAA) and the Frequency Control Commission (FCC), if a calibration certificate issued by MSL or by an IANZ accredited calibration laboratory is "traceable to the National Institute of Standards and Technology (NIST)". NIST is the US national measurement institute. Such a requirement is perfectly reasonable inside the USA, but causes difficulties when extended outside the USA, where measurement traceability is to the national metrology institute of the country in question, and not to NIST. In general there is a commitment for these regulatory bodies to rely on the CIPM MRA to decide on acceptable traceability. Certificates from MSL should be accepted, but the auditors may seek additional information.
