NMISA was established under the Measurement Units and Measurement Standards Act 18 of 2006 (The Measurement Act); to provide for the use of measurement units of the International System of Units (SI) and certain other measurement units; to provide for the designation of national measurement units and standards; to provide for the keeping and maintenance of national measurement standards and units and to provide for the establishment and functions of the National Metrology Institute.

The National Metrology Institute of South Africa (NMISA) underpins all accurate measurements for the country and the region contributing to the overall quality of life, trade and regulatory environments. NMISA is therefore responsible for ensuring measurement equivalence with the global system of measurement, the SI. NMISA, as part of South Africa’s quality infrastructure, is key in the operation of domestic markets and global competitiveness by ensuring the integrity of measurements conducted at various stages of the value chains of different commodities and manufactured products for the local and export markets.

The continued participation of NMISA and other South African TI entities in international technical infrastructure activities is imperative to ensure a solid technical infrastructure system that allows the economy to take advantage of export opportunities in a dynamic environment with rapid technological development and associated changes in regulations.
