The Accreditation Institute of the Republic of Macedonia became a member of the International Laboratory Accreditation Cooperation (ILAC) on December 1, 2008. Becoming a member of ILAC for the IARM is a confirmation that the internationally recognized criteria for performing accreditation activities are met, ie. confirmation that the IARM operates in accordance with international standards. Accreditation allows correct and correct decisions to be made when choosing a laboratory to perform certain tests. It enables the laboratory to demonstrate its competence, independence and ability to perform certain tests. The International Laboratory Accreditation Cooperation (ILAC) is an international organization of accreditation bodies that perform the accreditation of laboratories and inspection bodies. It was established 30 years ago and aims to help eliminate technical barriers to trade. It currently has accreditation bodies from more than 70 economies and regions. In 1977, the International Laboratory Accreditation Cooperation (ILAC) began as a conference to develop international trade cooperation. The idea of accepting test results and calibrations issued by accredited laboratories was promoted. In 1996, ILAC became a formal organization with a charter to establish a network of agreements for mutual recognition of accreditation bodies. Mutual recognition of accreditation bodies is aimed at recognizing test results and calibrations issued by accredited laboratories. ILAC agreements are now in force and governments can take advantage of them when signing trade agreements. The ultimate goal of ILAC activities is for the results of tests and calibrations obtained from accredited laboratories to be recognized by governments and industries in other countries whose accreditation bodies are not members of ILAC. In this way the idea of free trade would be realized, ie. The idea of a product once tested to be accepted everywhere in the world. Becoming a member of ILAC for the IARM is an obligation to constantly meet the requirements of international standards, and thus to organize its accreditation activities so that they are in function of overcoming technical barriers to trade.
