The range of certified products certified by NOM Certification

NOM's compulsory certification products are generally electrical and electronic products with a voltage of more than 24 volts of alternating current or direct current. It is mainly used in the fields of product safety, energy and thermal effects, installation, health and agriculture. The following products must be NOM certified before they are allowed to enter the Mexican market:

electrical and electronic products for use in homes, offices and factories;

computer local area network (LAN) equipment;

lighting fixtures; tires, toys and school supplies;

medical equipment; wired and wireless communication products, such as wired**, wireless**, etc.;

Products powered by electricity, propane, natural gas, or batteries.

NOM voluntary certification is generally applicable to parts such as conductors, fuses, lamp holders, and ballasts, and is used as a reference for manufacturers and importers.

Legal analysis: The NOM mark covers more than 2,000 product categories, and the setting of NOM standards involves the following areas: safety, health, environmental protection, communication, virtual information, energy efficiency, etc.

The NOM mark covers most electrical and electronic products, such as information technology equipment, audio and electrical equipment, household appliances, power supplies, lamps and other products that are potentially hazardous to health and safety. Electronic products with a voltage higher than 24V belong to the scope of compulsory certification, and electronic products with a voltage lower than 24V belong to the scope of self-praise certification.

Legal basis: Article 2 of the Standardization Law of the People's Republic of China The standards (including standard samples) mentioned in this law refer to the technical requirements that need to be unified in the fields of agriculture, industry, service industry and social undertakings.

Standards include national standards, industry standards, local standards, group standards, and enterprise standards. National standards are divided into mandatory standards and recommended standards, and industry standards and local standards are recommended standards.

Mandatory standards must be enforced. The State encourages the adoption of recommended standards.

According to Mexican law, the holder of the NOM must be a Mexican company responsible for the quality, maintenance and reliability of the products. The test report is issued by a SECOFI accredited laboratory, reviewed by SECOFI, ANCE or NYCE, and if the product meets the relevant regulatory requirements, a certificate is issued to the Mexican representative of the manufacturer or exporter in order for the product to be marked with the NOM mark.

TÜV Rheinland Mexico has partnered with a registered laboratory partner to carry out safety testing of the NOM certification process for a number of products: the scope of verification includes all electronic and information products and data processing equipment, but does not include household appliances (except microwave ovens).

NOM ANCE: The scope of verification includes that all electrical appliances and similar products (e.g. home appliances) are not subject to IEC standards, and NOM standards apply.

No EMC testing is required.

Walter is one of the few laboratories in China that has been accredited by Mexico** and ANCE and does testing directly in China. Contact **19867722117 ailsa

1.NOM mandatory sign.

Mexico only recognizes its own NOM safety mark (as shown in Figure 1), and the United States and Canada have no safety mark (such as CUL, ETL, CSA) that is recognized by the country**. Products that require mandatory certification can only enter the Mexican market if they bear the NOM safety mark.

Normally, the NOM logo is often used with NYCE or ANCE: - NOM NYCE: applicable to electronic products, communication products and data processing equipment, but excluding home appliances; —nom ance：

It is suitable for home appliances, including household electric instruments, electric hand tools, etc.

There are 7 authentication modes for compulsory authentication:

m0: certification through quality control and regular testing verification;

M1: Certification through regular testing and verification (new product type testing);

M2: Certification through quality system assessment verification (new product);

M3: Letter of conformity issued through periodic trial verification (for new products);

M4: Certification through quality control and periodic testing verification (for redesigned products);

M5: Batch certification (for redesigned products and used products without redesign manuals);

M6: 100% certified (for non-specification products).

In this certification mode, all tests are carried out every year. After passing the test, a NOM certificate will be issued.

The NOM certificate is usually valid for 1 year, after which periodic testing is required. However, if the certification procedure includes an inspection of the quality system, the certificate is valid for 3 years.

The certificate holder is usually a separate importer, manufacturer and distributor, and foreign manufacturers can apply for a certificate through a certification body recognized by the Mexican Standardization Committee.

1.The voltage in Mexico is 127V 60Hz

2.The plug is the same as the American plug. One is classi with three connectors, and the other is classii with two connectors. The plug will be tested along with the device itself.

The certificate is valid for one year and can be renewed annually.

When renewing the certificate, a random sample of a product is taken from the market in advance to be sent to the laboratory for testing, and the product packaging must contain the following information: product name, brand name, model number and NOM verification mark.
