An international laboratory proficiency testing program for Belt and Road partner countries was launched jointly by the State Administration for Market Regulation (SAMR), China National Accreditation Service (CNAS), and the United Nations Industrial Development Organization (UNIDO) on Thursday in Shanghai. Proficiency testing is an internationally recognized approach for technical exchange and cooperation in inspection and testing. It precisely identifies differences and issues across testing institutions in multiple dimensions, including equipment, interpretation of standards, and operational procedures. The program will focus on heavy metal contamination and veterinary drug residues, with lead, cadmium, chromium, and chloramphenicol as key testing items. SAMR has already organized authoritative testing institutions to prepare standard reference materials. The program is expected to involve nearly 40 official testing institutions from Belt and Road Initiative (BRI) partner countries.
