Colombia
The Superintendency of Industry and Commerce renders national standards official upon comparison with the international standards, as recommended by the General Conference on Weights and Measures. It also establishes agreements with foreign institutions for mutual recognition of certification and inspection organizations and testing and metrology laboratories. The national metrology standards are referenced to those of the Physikalisch Technische Bundesanstalt of Germany (PTB).
The basic documents for metrology activities in Colombia are, in the first place, those issued by the OIML; also used as references are the ISO standards, especially ISO/IEC Guide 25, the COPANT standards, and the recommendations of the International Electrotechnical Commission (IEC).
