The NMISA is part of the Department of Trade and Industry’s (the dti) family of Technical Infrastructure (TI) Institutes. Together the TI is responsible for the measurement standards and sciences, procedures and the regulations as well as accreditation that gives confidence in goods and products and allows for successful prosecution in cases of non-compliance.
South African Bureau of Standards (SABS): The SABS is responsible for the South African National Standards (SANS). These documentary standards rely on sound and validated methods (depended on accurate measurement) and are issued to assist the nation in all areas of life: health, testing, fuel, energy, etc. The documentary standards form the basis for regulators to legislate and enforce regulations and compulsory specifications.
National Regulator for Compulsory Specifications (NRCS): Responsible for the administration of technical regulations including compulsory specifications based on standards that protect human health and safety, and the environment. The NRCS also administers the Trade Metrology Act. The Act and technical regulations set the requirements for measurements of quantity for trade purposes (Legal Metrology). The outputs of scientific metrology are critical to the effective legislation and prosecution of regulations.
South Africa Accreditation System (SANAS): Responsible to give formal recognition that Laboratories, Certification Bodies, Inspection Bodies, Proficiency Testing Scheme Providers and Good Laboratory Practice (GLP) test facilities are competent to carry out specific tasks. A prerequisite for accreditation to ISO/IEC 17025 ‘General requirements for the competence of testing and calibration laboratories’, is that a laboratory must show traceability to the SI. Though traceability effectively could come from any country with a measurement system, the benefits of a national system supporting industry could and should not be underestimated.
