Mauritius Standards Bureau

Calibration

The Mauritius Standards Bureau is the custodian of all National Measurement Standards and is thus the Apex body within the National Metrological Infrastructure.

The metrology unit at MSB holds the primary measurements standards for Mass, Pressure, Force, Length, Temperature, DC Voltage and Electrical Resistance. The Bureau is responsible for Scientific and Industrial Metrology in Mauritius.
 
The main role of the scientific Metrology Laboratories is to maintain the status of all national measurement standards and to provide internationally-recognised traceability of measurement to all the stakeholders of the economy. It also has the function to  disseminate the values of the International System of Units (SI) through calibration services to all sectors of the economy.
 
The industrial Metrology laboratories offer calibration Services for measuring equipment in the fields of Mass, Pressure, Force,  Dimension,  Temperature and Electrical measurements on a voluntary basis against a fee.
 


 
Regional Affiliation

MSB forms part of the regional and the global metrological network through its membership with the Intra-Africa Metrology System (AFRIMETS) and the SADC Cooperation in Measurement Traceability (SADCMET), which are our Regional and sub-Regional Metrology Organisations respectively. These organisations are linked to the International Bureau of Weights and Measures (BIPM), whose responsibility is to ensure global uniformity of measurement and traceability to SI units.
 
International Affiliation

Mauritius, through scientific metrology activities at the MSB, is an Associate of the General Conference on Weights and Measures (CGPM), since October 2010. Mauritius is also a signatory to the Mutual Recognition Arrangement of the International Commitee on Weights and Measures (CIPM/MRA) since February 2011.

The processes, activities and submission of Calibration and Measurement Capabalities(CMC's) under this arrangement will lead the scientific Metrology laboratory to the international recognition of MSB's Calibration and Measurement Capabilities (CMCs) and calibration reports issued.

Currently the Scientific Metrology laboratories for Mass measurement and Temperature measurement are  involved in activities and processes leading to the submission of CMCs in the Key Comparison Data Base(KCDB) of the BIPM. 

The Quality system and technical capabilities of both measurement  laboratories have been assesed in 2016 by a team of assessors from AFRIMETS, our Regional Metrology Organisation (RMO).
The Metrology Laboratories participated in regional inter-laboratory comparisons as well as key comparisons of the AFRIMET to prove its established CMC's.

CALIBRATION SERVICES

The Industrial Metrology  Laboratories offer calibration of measuring equipment in the areas of Mass,Pressure,force,Length, Temperature and electrical resistance. 


ACCREDITATION Status
 
Currently, the Mass, Dimensional and Temperature Metrology Laboratories are accredited by the Mauritius Accreditation Service (MAURITAS) to ISO/IEC 17025 for a total of 9 measurement scope
