The task of standardization cannot be performed independent of standardization efforts in the rest of the world. This led UNIT to join the International Organization for Standardization (ISO), to participate actively in founding the Pan American Commission on Technical Standards (COPANT), and to win the recognition and representation of official international standardization organizations. UNIT's participation in ISO and COPANT enables the country to benefit from the results of regional and international standardization work, and inversely helping ensure that national interests and viewpoints can be shared regionally and internationally. Its participation in the organizations noted and the exchange of publications and advisory services among all the standardization institutions have led UNIT to collect 200,000 standards from all types of sources as material for consultation to achieve standardization. In the elaboration of its standards UNIT gives priority to standards of ISO and IEC, and when possible, those standards are adopted with no modifications. In the case of modifications they are introduced in the cover page or through footnotes, respecting integrally the text of the corresponding international standard.
COVENIN is based on international standards, particularly of ISO, IEC, and Codex Alimentarius, which serve as references in establishing its binding standards. Where there are no international standards on a particular subject, COVENIN looks for reference to the national standards of other countries and standards of internationally-recognized associations. The standardization system follows the international directives, especially the ISO/IEC directive 3 (drafting and presentation of international standards). At present the standardization system has adopted the Code of Good Practices for the Development of Technical Standards adopted in the World Trade Organization.
