Legal Frame

UL de México uses specific procedures when evaluating product compliance. Such procedures are based on the Federal Law on Metrology and Standardization (LFMN - Ley Federal sobre Metrología y Normatización), its Conformity Assessment Policies and Procedures (Políticas y Procedimientos para la Evaluacion de la Conformidad), MNX-EC-065-IMNC-2000, and UL requirements.

You can have direct access to these documents on the Secretary of Economy page, General Directorate for Standards (DGN - Dirección General de Normas).
