Mexico NOM

- NOM Mark safety approval for safety in electrical and electronic appliances
- Dictamene for ITE highly specialized equipment, refer to attachment 1

In accordance to the Federal Law on Metrology and Standardization, the NOM Mark is mandatory for most electrical and electronic products in Mexico. Copies of NOM Certificates are required by Mexican Customs Authorities to accompany each shipment into the country.

The NOM certificate is valid for one year, and is issued in the name of the Mexican importer of record, Mexican manufacturer, or Mexican distributor registered with NYCE or ANCE as applicable. For countries where Mexico has Mutual Recognition Agreement (MRA), the certificate can also be issued in the foreign customer’s name. Alternatively, for a small fee (refer to price list), TUV Rheinland de Mexico can arrange for a legal licenseholder registered with NYCE or ANCE. This arrangement is especially suitable for customers who have several importers where one test report/certificate must be issued for each importer substantially increasing the overall certification costs. In addition, arrangement is suitable for customers whose importers are not registered with NYCE or ANCE which delays the overall lead time due to special legal paperwork needed for registration.

Certificate renewal in Mexico may require random sampling and retest.

Technical country information

Rated voltage in the country 127V/60 Hz, for single phase and 220/60Hz for 3 phase circuits. The plug is identical to the US-plug. One plug type is of class I with 3 pins, one plug type is of class II with 2 pins. US Listed cord sets are acceptable. The cord set (plug, cord and connector is evaluated together with the equipment under test). The test reports must specify the temperature increase of the cord.

Industrial Machinery and EMC is not regulated in Mexico.

Standards

Testing must be done according to NOM standards by an accredited testing laboratory by “ema” the Mexican Accreditation Body www.ema.org.mx . Mexico is also a member of the CB scheme and ANCE is NCB and CBTL to IEC60335-1. They will accept CB Test Reports to that standard.

The certifications are issued by Mexican certification bodies:

Electrical appliances: ANCE (National Association for Certification) www.ance.org.mx
Electronic appliances: NYCE (Standardization and Electronic Certification) www.nyce.org.mx

The most popular NOM standards for testing and certification are as follows:

NOM-001-SCFI-1993: Electronic Equipment for Domestic Use with Input from Different Electrical Power Sources, - Safety Requirements and Testing Procedures for Class Approval. This standard is based on IEC 65-1985 as amended 1987.

Product Examples: Can opener, knife sharpener, air conditioner, UV/IR skin-treatment, massage apparatus blender, coffeemaker, warmers, toaster, hairdryer, electric drills, electric ovens and hair driers.

Note: For household refrigerators Safety and energy Efficiency approvals are mandatory under the standards NOM-003-SCFI (safety) & NOM-015-ENER (ennergy efficiency). For washing machines safety and energy efficieny are mandatory under the standards NOM-003-SCFI (safety) and NOM-005-ENER (energy efficiency) standards are regulated by the Mexican agency named CONAE (National commission for Energy Saving. Ffor reference go to: http://www.conae.gob.mx/wb/CONAE/CONA_1002_nom_publicadas_vigen.

During the validity of the NOM certificate, customer can apply to add models of similar construction , adding importers or adding license holders. No test is required if safety is not involved.

Family grouping criteria:


• Products must have the same supply voltage and electrical ratings

• Products must to use the same kind and number of batteries (battery operated products)

• Products must have the same physical and functional properties

• Products must have the same Protection Class (I, II, III)
