I. Overview of NOM certification  

NOM (Normas Oficiales Mexicanas) is a mandatory safety label in Mexico. It requires that imported products be tested and approved before being sold on the market.  Although the North American Free Trade Agreement (NAFTA) came into force on January 1, 1994, and Mexico's National Institute for Standardization and Certification of the Ministry of Electronics, in collaboration with UL and the Canadian Standards Association (CSA), published the North American harmonized standard, Mexico only recognized its own NOM safety mark.  American and Canadian safety marks (e.g. CUL,ETL,CSA) are not recognized in Mexico.  The product test visa must be issued by the Mexican DeccionGeneraldeNormas(DGN) or other recognized independent visa agency and must be recognized before the product can be imported.

The voltage in Mexico is 127V/60Hz, and the plug is the same as that in America. One is ClassI with three connectors, and the other is ClassII with two connectors. The whole machine should be tested with plugs.
