This document discusses conformity assessment and standards development in Mexico. It notes that the National Commission of Standardization (CNN) works with both the public and private sectors to develop National Standards (NOM) and Mexican Standards (NMX) through Standards Development Organizations (SDOs) and Technical Committees (TCs). It provides examples of specific NMX standards developed by ANCE for various electrical products that are based on International Electrotechnical Commission (IEC) standards and satisfy the essential safety requirements for those products set out in regulations like NOM-003-SCFI-2014. While technical standards may need to be updated, essential safety regulations remain the same. Participation in IEC standards helps streamline the national
