Calibration Service for the essential oils production value

The National Metrology Institute of South Africa forms part of the technical infrastructure support under the Department of Trade, Industry and Competition (the dtic). We work together with the South African Bureau of Standards (SABS), the South African National Accreditation System (SANAS) and the National Regulatory of Compulsory Specifications (NRCS) to enable the fair and safe trade of products and services in South Africa
